Potential energy of a system of 3 charges | Electrostatic potential & capacitance | Khan Academy

To calculate the electrostatic potential energy of a system of charges, we find the total work done, by the external agent, in assembling those charges. Since electrostatic fields are conservative, the work done is path-independent. And so, we can assemble the charges one by one, and calculate the work done in each step, and them together.
