Potential difference (or voltage) is a measure of energy, per unit of charge, transferred between two points in a circuit. A potential difference of 1 volt means that 1 joule of work is done per ...

Potential difference close potential difference (V)The amount of energy transferred by each unit of charge passing between two points of a circuit. The unit for potential difference is the volt (V).

Do you know the difference between potential and kinetic energy? I certainly don’t, which is why Dr. T, a Science Educator from the Springfield Museums, is with us ...
