Electric potential at a point in an electric field is defined as the potential energy per unit charge, and which is equal to work done in bringing a unit positive charge from infinity to that point.

∴ ϕ = W

Q. The work done in bringing at a unit positive charge from infinity distance to a point at distance $x$ from a positive charge $Q$ is $W$ . Then the potential $ϕ$ at that point is

$\frac{W Q}{X}$
