D) the difference in energy between a point and that of earth

Question

Quizplus · Accepted Answer

The volt is defined as the potential difference between two points in a circuit when one joule of energy is expended in moving one coulomb of charge between those two points. Therefore, it is defined in terms of the work done (one joule) in moving a charge (one coulomb) between two points.
