Investigating the change in resistance of a carbon paper Introduction The aim of this experiment is to see how the resistance of a carbon-coated piece of paper changes when the different variables change. Variables A variable is a change in an experiment that could alter the outcome/results of that experiment, and for this experiment the main variables are type of paper, width of paper, length of paper, and temperature. We are going to be studying how changing the width of the paper affects the resistance, and so to ensure a fair test we will have to keep all of the other variables constant, as if they were also changing the results could be affected and the experiment would not be of any use. We will therefore keep the type of paper the same (which is easy), will keep the length of the paper the same for each experiment (which is also easy), and also keep...
