- The standard metric unit of electric potential difference is volt, abbreviated V.
The potential difference is also defined as the work done per unit charge.
\(V={W\over Q}\)
Where V Potential difference, W is Work done, and Q is electric charge.
The S.I unit of work is joule and that of the charge is the coulomb.
