Question

.define the electric potential

Answer 1

The work per unit of charge required to move a charge from a reference point to a specified point, measured in joules per coulomb or volts is known as Electric Potential.

Answer 2

hi here is your required answer :-
 the electric potential difference is the difference in electric potential (V) between the final and the initial location when work is done upon a charge to change its potential energy. In equation form, the electric potential difference is 
ΔV= $V_{B}$ - $V_{A}$ = $\frac{WORK}{CHARGE}= \frac{ΔPE}{CHARGE}$

HOPE THIS WILL HELPS YOU
