Problem

A student performs three separate experiments to move charge between the same two points in a conductor. The work done WW and the charge moved QQ in each experiment are listed below: Set 1: W=3 JW = 3\,\text{J}, Q=3 CQ = 3\,\text{C} Set 2: W=5 JW = 5\,\text{J}, Q=4 CQ = 4\,\text{C} Set 3: W=0.8 JW = 0.8\,\text{J}, Q=0.8 CQ = 0.8\,\text{C} (i) For each set, calculate the potential difference between the two points. (ii) Classify each set as producing a potential difference that is (a) exactly 1 V1\,\text{V}, (b) greater than 1 V1\,\text{V}, or (c) less than 1 V1\,\text{V}. Justify your classification with numerical values.
