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.

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.
