Advanced Knowledge of Electrostatic Potential Energy and Potential Difference
Electric potentialElectric potential () at a point is defined as the amount of work done in bringing a unit positive charge from infinity to that point.
Unit of potential is .
Note: Potential is taken to be zero at infinity and at ground.
Work done by a given chargeWork done by a charge to move through a potential difference is given by .
Where = Final potential and = Initial potential
