Question

What are the units for the potential of an electric field?

Answer 1

Potential = V
Electric field = SI units of newtons per coulomb (N/C) or, equivalently, volts per metre (V/m).

Answer 2

Yes, SI unit of electrostatic potential is Volts (V). Electrostatic potential at a point is simply the work done by an external force in bringing a unit positive charge from infinity to that point.
