A charge of +1.4 × 106 coulombs moves from point A to B. What is the potential difference between the two points if the work done on the charge is +3.4 × 107 joules?
The potential difference between two points for a charge is given by the work done in moving the charge from one point to another divided by the charge. P.D. = E/q = 1.4 x 10^6 / 3.4 x 10^7 = 0.0412 V
