Macbeth-Struggle for Power

It is indeed evident that the play, Macbeth is ultimately about the struggle for power. Power is something many desire where people often change and become evil in their attempts to acquire it and during this play the characters go through many changes which lead to disaster. The two main characters mostly influenced by power in this Shakespearean play are Macbeth and Lady Macbeth. Macbeth is swayed by the prophecy made by the witches and also by Lady Macbeth who holds great control over her husband. Through the analysis of characters and techniques it can be seen that the desire of gaining power is evident in the play, Macbeth and that the characters stop at nothing to achieve their goals. Although the protagonist gains power there is still a constant thirst for more, to better their position one step further, even if it comes at the expense of a life. Macbeth becomes fixated on rising to the throne in place of King Duncan however; just recently, he has been given the title of thane of Cawdor by the king. Although happy with the new title and new power, Macbeth still craves for the role held by the king. The importance of honor in society is a primary theme as it is what provokes Macbeth to kill for kingship and sends him on a dismal journey towards the throne. â€Å"If chance will have me king, why chance may crown me without my stir†. (ACT I scene 3, lines 143-145) This demonstrates the ideology that Macbeth is not satisfied with just being a thane but has now heard the prophecy and is seduced by the thought of gaining more power. He hastily makes the decision to Kill Duncan with the influence of Lady Macbeth. Lady Macbeth's struggle for power starts the moment she appears in the play where she finds the letter and launches into criticizing Macbeth's manhood. â€Å"It is too full of o' th' milk of human kindness†. This metaphoric language mirrors the domineering character of Lady Macbeth where she accuses him of being too gentle to kill King Duncan. She believes this so much that she calls on evil spirits to remove Macbeth’s kind nature. â€Å"Hie thee hither that I may pour my spirits in thine ear and chastise with the valor of my tongue all that impedes thee from the golden round, which fate and metaphysical aid doth seem to have thee crowned withal. (Act 1 Scene 5, lines 23-28) Denoting that she is willing to cast out all that is righteous and dignified about her husband in efforts to gain power. She doesn't hesitate to execute the plan of murdering King Duncan because she believes the prophecy is true and that destiny is on her side. In search of power, the characters change and descend into a compulsive state which leads to disaster. As Macbeth falls deeper into this obsession with the throne he becomes a more dishonest and cunning character. â€Å"Who’s there? A friend†. ACT II scene 1, lines 11-12). This use of irony depicts the deceitful nature of Macbeth as he descends into madness. Banquo is a very loyal general to the King and he will not be tempted by Macbeth into betraying him. Macbeth is certainly no friend to Banquo, his murderous quest to kill Duncan contradicts Banquo’s morals and judgment. â€Å"Upon this bank and shoal of time we’d jump the life to come† (ACT I scene 7, lines 6-7). This metaphor exemplifies the idea that this shallow or narrow ford of human life in this great river of eternity. Shakespeare has creatively used symbolism through metaphoric language to demonstrate how a narrow river being cut off and dried up is Macbeth killing Duncan. He will be overthrowing the natural order of the heir to the throne and setting his place in eternity. Evidently he must kill King Duncan in this short period of time while he is still vulnerable in his castle. The effect of ambition on Macbeth drives him into his contemptible acts in order to assume the throne. He falls into a deep obsession which consumes his rational thought and he becomes very evil and conniving. Is this the dagger which I see before me, the handle towards my hand? † (ACT II scene 1, line 33-34) This foreshadowing illustrates the subconscious thoughts of Macbeth and how they materialize in front of him. He starts to visualize this dagger, predicting the malicious tasks ahead which add the disturbing atmosphere. Macbeth chooses to abuse his power over others and he becomes a hated king. This is caused not only by his cruelty but also the many superstitions by people who think he killed Duncan which greatly depleted his power. Lady Macbeth is quick to become evil in her ways as she is the mastermind behind the killing of Duncan. He that’s coming must be provided for, and you shall put this night’s great business into my dispatch† (ACT I scene 6, lines 64-66). These heartless puns convey Lady Macbeth’s merciless intentions for the night’s gathering. Being provided for often takes on the meaning of being fed but in this case Lady Macbeth is referring to the death of King Duncan. Putting the night’s business into her dispatch appears to be something along the lines of carrying out the welcome of the guests and of course she is indicating that Macbeth must follow her instruction in order to kill King Duncan. Ultimately it is evident that Macbeth is about the struggle for power where once you have gained a certain power you still yearn more, establishing a constant desire. When the characters are in search of power they become obsessive and this causes them to change and become evil. Therefore it can be seen that the importance and desire for power greatly contributes to the outcome of the play and the fate of the characters.

Macbeth sountrack Essay

In act 1 scene 5 is when Lady Macbeth found out the news about how Macbeth would become the Thane of Cawdor and king for the witches. I chose the song â€Å"I Want It All† by Queen to represent this scene. Part of the songs lyrics are â€Å"I want it all, I want it all, I want it all, and I want it now†. Lady Macbeth heard the news that he would be king and she right away wanted to accomplish that. She didn’t want to wait but instead she take the steps necessary to make Macbeth king as soon as possible. In act 1 scene 6 is when the king and others arrive at Macbeth’s castle to stay the night. I chose the song â€Å"Let Em In† by Paul McCartney to represent this scene. The songs lyrics are â€Å"Someones knockin at the door, somebodys ringin the bell, do me a favor, open the door and let em in†. This perfectly describes that scene because when King Duncan arrives Lady Macbeth is there to let them in. She already has a plan figured out for them and can’t wait to execute it. In act 3 scene 4 I chose the song â€Å"I’m Going Slightly Mad† by Queen to represent this scene. In the scene Macbeth is having a dinner party and notices that all the seats are taken. When he sees that his seat is taken by the ghost of Banquo he starts talking to the ghost who is invisible to everyone else. The lyrics â€Å"I’m going slightly mad† describe how Macbeth was acting really strange and made the guests question him. The ghost later came back and made Macbeth have an outburst again alarming the guests which sent them home. A symbol that is portrayed in this play is the weather. The weather plays a role in which if something bad is coming up a storm might appear. The song â€Å"The Thunder Rolls† by Garth Brooks reminds of when the witches would enter and a storm would move in. Also the night that Duncan got murdered, a terrible storm came in that night indicating that something bad happened. These natural occurrences are hints to the audience that something isn’t right and the song does a good job of describing a thunder storm. In act 1 scene 7 is when Lady Macbeth told Macbeth to be a man and kill Duncan. â€Å"When you durst do it, then you were a man; And to be more than what you were, you would; Be so much more the man†. I chose the song â€Å"I’ll Make a Man out Of You† from the movie Mulan. This song is about training men to become manlier and this is what Lady Macbeth wanted Macbeth to do. She wanted him to become manlier and do what she tells him. I chose the song â€Å"Tragedy† by the Bee Gees to describe the whole play. The genre of this play is tragedy and this song describes â€Å"when you lose control† of everything. Macbeth took things too far and lost everyone that was close him. The lyric â€Å"With no one beside you, you’re goin’ nowhere† reminds when Lady Macbeth died then he really didn’t have anyone else. Since he had no one with him for support, the only way he could go was down.

Golden Gate Bridge History Essay

The First proposal for the Golden Gate Bridge came from James Wilkins, who at the time was an engineering student. The cost of James Wilkins Bridge was unrealistic at the time which was 100million dollars, but none the less it set the bar for other bridge engineers to try to work out a cheaper solution. During this time a young Joseph Strauss had graduated from the University of Cincinnati with a degree in Business and Economics. Joseph was an avid student at his school and was the class president and poet for his class. Joseph’s interests with engineering and bridge design some might say happened by chance, in that, one day Joseph once tried out for his school’s football team but got injured and taken to the infirmary. During his stay, he gazed outside the window at the Cincinnati-Covington Bridge. Little did anyone know, Joseph was on his way to becoming a leader in his society and a hero amongst most. Joseph spent some time working at an office for an engineering fir m which designed bridges, and after a preposition to his firm was rejected, he though to start his own firm and take his idea with him. Joseph went on to create the Strauss Bascule bridge company of Chicago where he amped up the modern day bascule bridge (draw bridge) with his designs and ideas. At the Strauss Bascule bridge company of Chicago, Josephs worked on the Burnside Bridge in Portland in the year 1926, the Lewis and Clark Bridge in 1930, the Cherry street Strauss and Trunnion Bridge, the Washington Street Bridge, the Hoquiam Bridge, the Skansen Bridge and finally worked as the chief engineer on the golden Gate Bridge. All of this was done without a proper degree in engineering. Joseph first tackled the idea of designing the Golden Gate Bridge with a plan of having two double cantilever spans linked by a central suspension segment. This design was rejected and later on a fellow engineer working on the project under Joseph by the name of Leon Moisseiff came up with the Final Design for the Golden Gate Bridge. Joseph was a very conservative man and left plenty of room for error throughout the entire process of designing and building the Golden Gate Bridge. Joseph insisted that a net be placed under the work space to catch workers who accidentally fell off. This net tha t he implemented saved a total of 19 lives and he was commemorated more than ever for it. Joseph received a statue at the end of the Golden Gate Bridge on the San Francisco side. Leon Moisseiff received the Franklin Institute’s Louis E Levy Medal in 1933 and was a leading suspension bridge designer within America. Leon graduated from Colombia University with a degree in civil engineering in 1895. Leon had a number of bridges which he has worked with but to name a few of most notable were the Manhattan Bridge and the Benjamin Franklin Bridge in Delaware. Leon Moisseif was best known for his work with the deflection theory which simply stated that the longer a bridge spans the more room it has to wiggle and move. He applied this principle on the Golden Gate Bridge as it was to span a length no bridge has spanned before at the time. Moisseiff was mainly in charge of the calculation of force revolving the wind the Bridge would have to withstand and one of his co-workers, Charles Ellis was a big believer in Moisseiff and his â€Å"Deflection Theory†. Charles Ellis was first appointed onto the Golden Gate Bridge project by Strauss himself. Strauss recognized him as a well renowned scholar of mathematics but as ironic as it is, Ellis like Joseph Strauss never received a degree in Engineer either, but one thing Ellis had on Joseph was a certificate in the field. Charles had fallen in love with the engineering and went on to write a book named â€Å"essentials of theory in framed structure† which became a mandatory text for Harvard and Yale engineer students. Charles graduated from the University of Wesleyan with a degree in Greek and Mathematics. Charles worked as a professor of engineering at the University of Michigan and the University of Illinois for some time. Ellis was a key part in the construction and design of the Golden Gate Bridge but Joseph made an alarming move which was controversial. Joseph accused Ellis of wasting time and money on the project and ordered Charles Ellis to take a vacation from work, and near the end of it Ellis received a letter from Joseph telling him not to come back to the job. Ellis was devastated and was still much attached to the project. After he had been released he began teaching at the University of Perdue and on top of his teachings kept working at problems and overlooking the designs for the Golden Gate Bridge dedicating around 70 hours a week. He found several errors which raised some eyes brows and in no time sent a letter to Moissieff. Charles Ellis was given almost no credit for his 3 years dedicated to working on the Golden Gate Bridge. His name was not mentioned on the list of builders but until recently was given a plaque acknowledging his participation in the bridge design. How the Golden Gate Bridge affected the local community. The Golden Gate Bridge is a historic achievement of great magnitude in the San Francisco and California region. It has created many jobs for the locals as positions were promised to be favouring them and also had brought attention to the area from all around the world. A total of 10 construction companies were called into the building of the bridge and materials from all over the world were brought in and in tremendous amounts, 83 000 tons of steel and 389 000 cubic yards of concrete. Conclusion The Golden Gate Bridge is a Remarkable piece of engineering. It has come a long way over its 4-5 years of construction and not to mention all that was needed to set its plan in motion. It has faced many obstacles to get to where it is at today, being one of Americas most recognizable attractions. The Golden Gate Bridge pushed the limits of its time, being the longest, highest bridge of its time really opened the eyes of many people in what exactly careful engineering can accomplish. It has had lots of passionate dedicated workers behind it since day one and along the road had its ups and down but in the end turned out to be one of mankind’s greatest accomplishments.

A&P Topic - Essay Example The use of an extremely low temperature stops every single biochemical process inside the cells including apoptosis and cell death procedures, thus the cells can be stored in a stagnant state for long periods of time till they are thawed for use. The temperature needs to be as low as -196˚C and the medium used now is liquid nitrogen. However, cryoprotective agents like DMSO and glycerol are used now to prevent intracellular freezing. Cells like microbial cells (protozoa, fungi spores etc), animal cells (oocyte, sperm, embryo etc) and viruses have been successfully cryopreserved till date. Cryopreservation is a boon for scientific development. Pregnancies have been possible using 20 years frozen embryos and ovarian cells can be stored to help women to conceive even after menopause. Cryopreservation of microbes is being conducted to add data to bio-bank, thus making it possible to study something even if it becomes extinct. Another extremely important use for cryopreservation is, pr eservation of stem cells. If a new born’s stem cells (extracted from placenta) are preserved, they can be used for surgeries in his lifetime thereby eliminating surgical complications. Wildlife scientists are also contemplating to use this technique to save endangered species and clone some extinct ones. My first brush with Anemia was when I was inflicted by it. That is when I came up close and personal with the disease and gained information about it from my doctor. The most important transport fluid in the human body is the blood and the composition of which is complex and intricate. Anemia is the most common blood disorder which arises when there is a decrease in the number of RBC’s or in the amount of hemoglobin in the body. Since the primary work of RBC’s is to supply oxygen, shortage of it causes oxidative stress in the cells which leads to further clinical complications. The degree of the disease depends on the severity and the type of

VH Case Study Example | Topics and Well Written Essays - 750 words

VH - Case Study Example One of the major risk factors pointed out is that the management is old and unproven. The CEO is too old, that is about 70 years, and the CTO is his son. However, as far as Telco Exchange agrees to change the CEO and appoint someone who is suggested by Valhalla, this risk is solved to a great extent. The scope of the field Telco Exchange is engaged in is evident from the Aberdeen finding that while the average profit of a Fortune 500 company is 1% of its revenue, the money the company spends on telecommunications is around 0.84% of the total amount. So, as far as Telco manages to provide highly integrated and comprehensive solutions, there will be growth, or, at least, the business will not go down. Though there is a possibility that some financially able competitors like MSS Group, Teldta Control, Profitline, and QuantumShift may try to develop software solutions, they will address only the financial part of the issue, thus failing to address inventory management and service order. So, there is no possibility of any serious threat to Telco Exchange in the near future. Hence, Art Marks can vote to invest in Telco Exchange. B. ... However, as the companies know, these are not complete solutions as they do not address the root cause of the problem. On the other hand, Telco Exchange offers a much more comprehensive and integrated solution that identifies the root causes and the unnecessary services and equipments. It also helps prevent erroneous ordering and make sure that the elements which are not needed are eliminated. In addition, it provides a holistic view of the communication infrastructure of the companies. Furthermore, Telco Exchange helps automating the ordering process, thus making the data available for all parties to work with. This helps to ensure that the corporate policies are properly followed. Thus, it becomes evident that the outsourcing approach will not provide a solution that is as effective as that of Telco Exchange, and hence not a risk. The third risk is that the present management is unproven, with a CEO aged 70. In addition, the CTO is his son. It is necessary for the company to change the existing management, however, without any effect on the existing customers and performance. C. The Valhalla due diligence is perfect in the fact that though it may fail to provide huge profit through investment based on wild assumptions, it takes maximum care on not losing the investment. Thus, investors are offered an investment that is free from risk to the maximum possible extent. The investment decision is taken after duly studying the investment memo, and to take the decision, the whole board should vote unanimously; not based on majority. This ensures that all issues and risks concerning the investment are fully analyzed and not even a

Micro controller -2 Assignments - Assignment Example A tool has been used to stipulate guidelines that guarantee little environmental collateral damage or harm at all, when implementing new development mechanisms. As such, it bears tremendous significance in exhibiting sustainable advancement (Cirp International Conference On Life Cycle Engineering, Nee & Ong 2013, 25). The Life Cycle Assessment is a cradle-to-grave technique that is used to assess and analyze the effect of production stages on the environment. It stipulates a detailed comparison of the services and products effects by making an analysis of the outputs and inputs alike. According to Baumann and Tillmann (2004, p. 1), it is an effectual technique that comprehends the environmental impact of a product through its Life-Cycle. The Life Cycle of a product hence starts from its phases of production, through to use with the eventuality of management of waste. The stages of the Life Cycle of a product/development are covered in the presentation below: Expression of the concerns of diminishing raw materials and sources of energy in 1960s led to the creation of LCA. The intent was to stipulate accounts for energy use in a cumulative manner and to give projections for the extensive future supply and use of resources. According to Schaltegger et al. (1996, 15), the first LCA publications presented by Harold Smith, covered calculations of requirements for cumulative energy for chemical intermediates production. The presentation was made at the 1963 Global Energy Conference. The later stages of the decade witnessed publications that made predictions into the repercussions of the changing populations of the world on the demand for energy resources and raw materials. Understanding the calculations of industrial energy use resulted from the predictions of the possibility of the depletion of the fossil fuel reserves and

St. Matthew's Passion by Bach Essay Example | Topics and Well Written Essays - 750 words

St. Matthew's Passion by Bach - Essay Example The music was text bound and therefore difficult to measure because of its spiritual and expressive intensity. Bach was counterpoint master as he used all baroque era musical language resource with ease. He could combine Germany intricate counterpoint, French rhythmic dances and graceful melodies of Italy in a single composition. Some of his work include Christmas oratorio which include St. Matthew Passion and ascension cantata (six cantatas) (Robin, 1999). Master of St. Matthew Passion It is an oratorio written by Bach for orchestra, choir and solo voices. Matthew’s gospel chapter 26 and 27 are set into music with arias and chorale that are interspersed throughout the musical text (Robin, 1999). Composition The setting of Bach’s passion present chapter is in 26 and 27 of Matthew’s biblical text in a simple manner by use of recitative. In addition, latest poetic texts are set by ariaso and aria movements which explain various biblical events in a narrative form ( Robin, 1999). Lyrism and monologue are used to present the state of mind of the characters that are involved. St. Matthew Passion has the following aspects: a) Double-choir which originate from double-choir motets. b) Chorales are used extensively and appear and are found in four parts as an arias extension. In polyphonic movements which are large, chorales appears as cantus firmus. This quite evident in the finale of the first movement Mensch, bewein dein’ Sunde gro?. Chorale cantus firmus is also used in opening chorus, as Kommt, ihr Tochter, helft mir klagen where soprano in ripieno create harmonic and polyphonic anxiety, singing O Lamm Gottes, unschuldig verse (Robin,1999) The oratorio is a twelve score concertato with eight soloists performing in two choirs(Robin,1999). Furthermore, extra parts have two bass and single soprano voices in the bit parts which include Peter, Pilate Wife, High Priests, and Judas with another section for soprano in ripieno. vocal ensembles has three voice parts (three basses, three tenors , three sopranos and three altos and residual which has two parts that provide soloists ( Concertists) for the composed cantatas together with other vocal works. Secco recitative is used in the gospel narration with continuo accompaniments (Robin, 1999). Words describing various characters are sung in recitative form. Apart from Jesus, other named parts, include two ancillae(maids),two witness, Judas, two high priest, peter and Pilates’ wife. Arias are often assigned to character soloist who sings with the choir(Robin,1999). In addition, a pair of soloists sings the two duets which concurrently represent two speakers. Turba (Crowd) are passages for many speakers and is sung by either one or two choirs. There is special treatment for the words of Jesus Vox Christi. This is by creation of accompagnato recitatives which are accompanied by continuo and orchestral string section by use of long notes that are sustained and stressing sp ecific words (Robin, 1999). Instruments St Matthew Passion has a setting of two orchestras and two choirs and it include two Gamba, two flutes, and two oboe and basso continuo. Instruments create a particular mood in arias for example Aus Liebe will mein Heiland sterben which is #49 soprano arias where there is no security as a result basso continuo and string absence (Robin, 1999). Compositional style Recitatives create a mood

Financial Year runs from 1 April in one year and ends on 31 March of the following year. For taxation purposes, taxable profits by a corporation for Financial Year 2008 are those obtained from 1 April 2008 to 31 March 2009. Income tax is a tax on income. Not all income is taxable and you're only taxed on 'taxable income' above a certain level. Even then, there are other reliefs and allowances that can reduce your Income Tax Bill - and in some cases mean you have no tax to pay ("Income Tax - the Basics"). Non - taxable income are certain sorts of income that you never pay on tax. These include certain benefits, income tax exempt accounts, Working Tax Credit (WTC) and premium bond wins. These income sources are ignored altogether when working out and how much Income Tax you may need to pay.

Storage device Essay Example | Topics and Well Written Essays - 500 words

Storage device - Essay Example RAM, graphic card memory and cache are the common primary storage devices, and they hold data from secondary devices while it is being used by the computer. The primary memory does not store data for future use due to its small size and lack of capability to store data permanently since they require continuous electric current as opposed to magnetism in secondary devices. RAM has high speed and is accessed with minimal delays due to its direct connection to the CPU via memory buses. RAM is mainly used to store data located in programs and operating system and hence it is necessary that every computer has a secondary device for data storage. Secondary storage is also known as auxiliary storage and is defined as any storage devices that are volatile and may be located inside or outside the computer. Secondary storage devices serve as an addition to the primary memory, and their function is to store data permanently. Secondary storage devices can store data ranging from megabytes to petabytes depending on their storage capacity (Matick 18). Such devices store the installed applications, the operating system, drivers and any other information that the computer user is willing to save. Secondary storage devices do not have a direct connection to the CPU and instead they receive and send data to the CPU through I/O buses. The speed of the secondary storage devices is considerably as compared to that of the RAM and hence cannot transfer data quickly. These devices are advantageous since they store data magnetically, and it is retained once the computer is switched off. The most common type of secondary storage device is an internal hard drive, but there exists many other forms of secondary storage e.g. DVSs, floppy disks, external hard disks, am flash discs. Most secondary storage devices have speeds ranging from 3600RPM TO 7200RPM and are nonvolatile therefore being reliable in data storage and backup (Matick 18). Hard disks are advantageous because they are normally

What are the pros and cons of the rise of networks Essay

What are the pros and cons of the rise of networks - Essay Example To put it simple, â€Å"a network society is a society whose social structure is made of networks powered by microelectronics-based information and communication technologies.† In this definition, it is evident that network as an essential part of social structure has a two-fold basis for its functioning. In this context, it is necessary to concentrate on the reasons of network to empower. In fact, this argumentation enables to comprehend the core contradiction that appears with the rise of networks. Among the key drivers towards the new network society, Castells (2010) mentions technological revolution, growing interdependence between contemporary economies.In other words, â€Å"social changes are as dramatic as the technological and economic processes of transformation†.In the case of technology, the very ability to analyze innovations in the close link with social movements rejects technological determinism. In particular, it is presented as a deeply rooted in the so cial fabric instance, which is a mirror of prevailing type of social and economic knowledge, organizational framework, and network disposition (Castells, 2010, p. 35). In the context of the latest technological revolution, Castells (2010) emphasizes the role of Silicon Valley in America as a precise driver of this significant change (p. 62). Moreover, he stresses on the genetic engineering as â€Å"they also refer to the decoding and recoding of the information of living matter†.

The Politics and Sociology of Media and Culture Essay

The Politics and Sociology of Media and Culture - Essay Example However, a particularly vulnerable sector or demographic are adolescents, not only because of the access they have to virtually all forms of media – such as the internet, television, radio, newspapers and magazines – but also because they are at an age where they are particularly vulnerable. They have yet to develop sufficient maturity and discernment necessary to filter out potentially destructive messages and unhealthy ideas streaming in from various media sources. One such threat to adolescents in particular and to the general viewing public in general are reality TV shows. There have been a slew of reality TV shows out in the market over the past few years. Some of them test one’s physical mettle like Amazing Race, others have to do with the search for love like The Bachelor or The Bachelorette, others test one’s aptitude in various fields of endeavor like The Apprentice, and yet others talk about undergoing physical transformations like The Swan, a reality TV series in the United States produced by Fox TV. The show â€Å"The Swan† is rife with political and sociological meaning. While it is indeed very entertaining and riveting, it is loaded with so many negative messages that present trouble for the impressionable adolescent girl-child. First of all, it breeds stereotypes. It has long been established that factual and fictional media portrayals have a propensity to activate culturally shared racial and gender stereotypes and affect judgment involving those who belong to stereotyped groups

Good conductors of electricity Essay Example for Free

Good conductors of electricity Essay EXPERIMENTAL PROCEDURES In order to record my observations, I will use the following types of observation tables, and I will display the manner in which my wire will be setup, in order that I will be able to experiment with them. 1. LENGTH For length, we have to make sure that only the length is changed, and that all the other factors are kept as a constant, i. e. the thickness, the material, and the temperature. Thickness = 0. 3 mm Material = nichrome Temperature = room temperature The index is adjusted, to vary the resistance, 10 alternative readings of current and voltage are taken, at uniform intervals. For every 0. 2 volts, I will be measuring the current, for each wire, and I will be observing, and recording the readings on the ammeter, in a table like this. SR. NO VOLTAGE CURRENT AVERAGE R= V / I IN VOLTS(V) INCREASING DECREASING CURRENT (? ) 1 0. 00 Xxx Xxx Xxx Xxx 80 X 11 2. 00 X TOTAL AVERAGE RESISTANCE = Xxxx My expected graphs will look like this. The shorter the wire, the lesser the resistance there will be. ? = 1/ gradient ? 20 cm wire has the greatest gradient, so less resistance. The resistance on should tally with my table readings; otherwise, it will mean that there is an error somewhere. 2. Thickness For thickness, we have to make sure that only the thickness is changed, and that all the other factors are kept as a constant, i. e. the length, the material, and the temperature. Length = 50 cm Material = nichrome Temperature = room temperature SR. NO VOLTAGE CURRENT AVERAGE R= V / I IN VOLTS(V) INCREASING DECREASING CURRENT (? ). 11 2. 00 X TOTAL AVERAGE RESISTANCE = Xxxx My expected graphs will look like this. The thicker the wire, the lesser the resistance there will be. ? = 1/ gradient ? 3 mm wire has the greatest gradient, so it has the least resistance. 3. Material For material, we have to make sure that only the material is changed, and that all the other factors are kept as a constant, i. e. the length, the material, and the temperature. Length = 50 cm Thickness = 0. 4 mm Temperature = room temperature SR. NO VOLTAGE CURRENT AVERAGE R= V / I IN VOLTS(V) INCREASING DECREASING CURRENT (?) TOTAL AVERAGE RESISTANCE = Xxxx My expected graphs will look like this. Different conductors have different resistances, thus, the copper wire has the greatest gradient, and so it has the least resistance. In order to increase the reliability of my resulting readings, I am going to record the readings while increasing and decreasing the voltage supplied. I will also make use of series and parallel circuits, to verify the law of resistance. To investigate the law of resistance for length. I will use the following type of board for this. The resistance for the 25 cm wire is shown by : The resistance for the 50 cm wire is shown by : This the type of graph I would be expecting to get. As you can see, the line for the 20+30 cm graph falls just a little short of the 50 cm. R = R1+ R2 In addition, to verify the law of resistivity for thickness, we use parallel circuit, which are connected in this manner: Here we will test to see if the resistance of two . 4 mm wires connected in a parallel, is equal to the resistance of a .56 mm wire. This should get me a graph like the one that follows: In order to plot this type of graph, I will have to record my results in a table like this: The resistance for the 0. 4 mm + 0. 4 mm wire is shown by : The resistance for the 0. 56 mm wire is shown by : I did a prior test, or an introductory pre experiment test, to get me used to how to know to work the rheostat, and connect the circuit, and the results I got, are on the next page. Analyzing evidence As you can see from my graphs, which are more or less like the graphs, I had expected to get, in my planning,In order to show that when the length of the wire was changed, the resistance changed proportionately, I created this bar graph. Thus as you can see, when the lengths in crease, the resistance of the wire increases, as there are more collisions between the electron, (which is moving from the negative end to the positive), and between the atom. When length is doubled, resistance doubles. Therefore length is directly proportional to resistance. In addition, I compared the resistance obtained from the tables, when I changed the thickness of the wire, and this is the resulting pie chart. Here too, it is plain to see that when the thickness doubles, the resistance is halved. This is due to, when the thickness increases, there is more space for the electron to pass through, without colliding, and thus resistance decreases. Thus resistance is inversely proportional to resistance. Where as in my series and parallel graphs, the gradient achieved for both the graphs is almost the same, thus I state that the resistance of a longer wire, is the same as two shorter wires connected together in a series circuit. In addition, the resistance of a thicker wire is the same as that of two thinner wires connected in a parallel.
