Question

State and define the SI unit of potential.

Answer 1

1. The SI unit of electric potential is the volt, which is defined as a joule per coulomb.
2. The SI unit of potential or potential difference is Volt. One Volt may be defined as the one joule of work done to move a charge of one coulomb.
3. Electric potential energy is a scalar quantity and is defined as the total potential energy a unit charge will possess if located at any point in outer space.

The general formula of Electric potential is

Electric potential (V) = Work done to move a charge from one point to another / charge.
