potential difference is the difference in electric potential (V) between the final and the initial location when work is done upon a charge to change its potential energy. 1 The potential difference can be calculated using the following equation; [2] Where is the work per unit charge done on a charge Q moving it from one point to another against the electric field. If the distance is small the potential difference can be calculated using; [3] If there is no current flowing through a surface, then that surface is said to be an equipotential surface. Current is what causes there to be a potential difference because it is what moves the charges from one point to another. Now potential difference and electric fields can be in three dimensions. But, for the sake of simplicity, the lab has been designed to determine both of these quantities in two dimensions so that we can gain a better understanding of the topic at hand. Equipment: 1.
