# Electric Potential Due to Discrete Distribution of Charges

Suppose we have q_{1}, q_{2}, …..q_{n} are the electric charges distributed discretely and r_{1}, r_{2},……r_{n} are the position vectors, respectively, then electric potential at point P due to electric charge q_{n} is calculated as below.

The total electrical potential at point P is the sum of all electrical potential of all charges of distribution.

V = V_{1} + V_{2} + ………….+ V_{n}
