I determine the resistivity of constantan and compare it to a data book value.

Introduction it is proposed that there are factors that influence the extent to which metal wires carry electrical current in circuits ie the length of the wire, the cross- material is resistant to the flow of electricity and low values of resistivity imply not associated with the experiment were kept away (a risk assessment was. Introduction first before starting my coursework i have decided to choose a factor that will affect the resistance of a wire i shall do this by going through all of the factors that affect the resistance of a wire and how i would measuring each factor to find out which would be the most effective and easiest factor to measure. Experiment 4 resistance and resistivity a slide wire wheatstone bridge is used to determine the resistance of coils of wire made from different materials analysis use (5) and (7) to determine the resistivity of copper, german silver, and nichrome if uncertainties are to be calculated, then the value of lac in (5) is.

Resistance of a wire coursework conclusion the resistance of a wire is directly proportional to its length and will not be able to make a proper conclusion relating to wire length toggle navigation skip to content podcasts about us write my position paper for me collaborators im doing my resistance of a wire coursework and. The wire used to connect the circuit contains resistance, so thicker wire should be used to reduce the resistance, so a more never close the switch while the connection is being made conclusion ◦ based on the result of experiment, the internal resistance of the cell was 111 ω and the emf e of the. Resistance by measuring and recording the wire's current and voltage in volts and amps on various stages of the experiment stages: voltage: 10 battery eliminator reading: 108 ∴108-10=08 v science investigation task: resistance 10 data representation and analysis: o graph 01: the graph represents the. Design and conduct an experiment to find the relationship between one of the most easily controlled independent variables and the total resistance of a wire ( the dependent variable) design your experiment, collect appropriate data, graph it, and by performing regression analysis, find the physical law print a single.

How the resistance of a wire is affected by its length this investigation will determine how changing the length of the wire, when passing an electrical current through it, will effect its resistance resistance- “the property of failing to conduct electricity or thermal energy” introduction in the conduction of this experiment i will. Electrical currents are routinely harnessed and transmitted via interconnected wires the purpose of this research is to identify factors commonly responsible for affecting the resistance of current, or flow of electricity, across a wire in an electrical circuit some factors will need to be identified and investigated.

So i will use 20, 22, 24, 26, 28, 30 and 32 swg wires for my experiment measure resistance apparatus metre rule wires with different thicknesses 6v battery ammeter voltmeter (0 to 10v) crocodile clips 5 connecting leads heat proof mat i do not know how big the current will be so i will start by using. Introduction: resistance is a force, which opposes the flow of an electric current around a circuit resistance is measured in ohms george ohm discovered that a circuit sometimes resists the flow of electricity he called this 'resistance' he even came up with a rule for working out the resistance of a circuit, which was.

  • Perform a similar experiment to produce a table of diameter, d and resistance, r for constant wire length note: cross sectional area analysis – part a plot a graph resistance, r on the y-axis versus length, l on the x-axis 1 give your graph a title 2 join your points with a line of best fit (trendline) 3 what does your graph.
  • From this we may conclude, that, if the original resistance is to the final resistance in a greater or less ratio than the square of the resistance of these thick wires was found to be 036 ohms experiment 1 this experiment was made with copper wire 628 millimetres in diameter it being the first experiment i made, all the.
  • Investigating resistance of a wire the aim of this experiment is to find out how the resistance changes as the length of wire changes within the circuit changes at the end of this investigation i will come to one of five possible conclusions which are: -the resistance increases as the length of wire increases, or -the resistance.
