Question

Define electric potential and write down its dimension.

Answer 1

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,

$\frac{W}{Q}=\frac{F.d}{Q}⟹M{L}^2{T}^{-2}{C}^{-1}⟹M{L}^2{T}^{-3}{A}^{-1}$
