Define electric potential and write down its dimension.
Definition:-
The electric potential is the work per unit of charge required to move a charge from a reference point to a specified point.
It is measured in joule/coulomb or volts.
It is also define as the work required to transfer a unit positive electric charge from an infinite distance to a given point against an electric field.
For dimensions,
WQ=F.dQ⟹ML2T−2C−1⟹ML2T−3A−1
