Physics Coursework 2002 Planning Introduction Aim: To investigate the resistance of a conducting material as its length changes. I am carrying out this experiment to find out if as a result of changing the length of a conducting material - graphite paper in my case, the resistance changes directly because of this change. In order to make sure that the results, leading to further conclusions, are reliable, I must make sure that any other factors that could possibly affect resistance are kept constant. Variable Studied - Length I will be using a circuit method in this investigation; there are a number of different factors that I must take into account when investigating the resistance of the graphite paper. Obviously, the first is length, which I will decrease from its starting length in equal steps as it approaches zero centimetres long; this is the main variable being considered in my investigation. The width of the...
