Derive the potential difference formula in Physics.

In an electrical circuit, the electric potential difference between two points (E) is defined as the amount of work done (W) by an external agent in moving a unit charge (Q) from A to B.

The Unit of potential difference is joules per coulomb, which is also given the name volt (V) after the name of Alessandro Volta.

So, the formula for Potential Difference is: E = W/Q

Where,

E = Electrical potential difference between two points,

W = Work done in moving a charge from A to B.

Q = Quantity of charge in coulombs.
