Solution
The unit of electric potential is joule/coulomb.
Explanation:
Electric potential is the work done per unit charge in bringing a positive test charge from infinity to a given point. Therefore, its SI unit is joule per coulomb (J/C), which is called volt (V).
\[ 1\,\mathrm{V}=1\,\mathrm{J/C} \]
