Answer:

The difference in values of electric potential between any two points is called the potential difference between the two points.

Explanation:

Owing to it's irrotational nature (i.e. #nabla X vec E = 0#), the Electrostatic field can be expressed as a gradient of a scalar potential function.

Thus, #vec E = -nablaV# where #V# is the potential function and the - sign is introduced for convenience and consistency.

Thus, the potential function can have various values in various points in space.

If #V_A# and #V_B# be values of the potential at A and B respectively, the potential difference would be,

#V_A - V_B#
