E)the work per unit quantity of electricity.

Question

Quizplus · Accepted Answer

The concept of difference in electric potential or voltage, is defined as the work per unit quantity of electricity required to move a charge from one point to another in an electric field. It is measured in volts (V) and is the driving force that causes electric charge to flow through a circuit. A potential difference of 1 volt means that 1 joule of work is done per coulomb of charge moved. Therefore, option E is the correct choice.
