Question

define potential difference, derive it expression​

Answer 1

Answer:

Mark me as a brilliant

Explanation:

The potential difference between points A and B, VB − VA, is thus defined to be the change in potential energy of a charge q moved from A to B, divided by the charge. ... Units of potential difference are joules per coulomb, given the name volt (V) after Alessandro Volta.

Answer 2

The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies.
