Physics Coursework- Ohm's Law Aim: To investigate the factors of affecting the resistance of a wire. In this experiment I will be using a metal nichrome wire to show the resistance when the length and width is changed. Variables Variables that I am going to keep the same. Variables that I am going to change. Width- 0.36mm2 Material- Nichrome wire Voltage- 2V Temperature- Room Temperature<Tab/> Length- 10cm, 20 cm, 30cm, 40cm, 50…showed first 75 words of 2376 total…

…showed last 75 words of 2376 total…use my method to construct the same experiment to try and prove my prediction from any mistakes or faults. My second and third results were mostly similar to the first set of results for both width and length, but there were some readings off by a couple of ohm's, which could have been accounted from misreading, although I believe I have enough results to prove my prediction but it can be repeated for more reliability.
