Expert Answer:

Potential difference: Potential difference between two points is defined as the amount of work done in moving a unit positive charge from one point to another. Potential difference between two points is also equal to the product of the electric field and the distance between the two points.

V = E.d

It is measured in Voltage or simply volt (V).

Potential difference is mostly used in the study of current electricity.


Both electric potential and potential difference can be expressed in V and Nm/C.
