Concept of Electrostatic Potential:

The electrostatic potential (V) at any point in a region with electrostatic field is the work done in bringing a unit positive charge (without acceleration) from infinity to that point.

Electric Potential due to a System of Charges:

The potential V at any point P due to the charge configuration is the algebraic sum of the potentials due to the individual charges This result is a direct outcome of applying superposition principle for a number of point charges.

Working of a Capacitor:

So what is the physical significance of a capacitor's capacity to retain charge and energy? Whenever a capacitor is charged by applying a potential difference, it stores energy. This energy can be used where a quick surge of energy is needed, like camera flash, motor starters, etc. Let's see the working of a capacitor at microscopic level by considering the charge build-up, then storage and then discharging.

Series and Parallel Connection of Capacitors:

Capacitors of capacitance can be combined to obtain a system with some effective capacitance C. Two of the simplest possible configurations are series ()and parallel (). Let's see how we find the expression of their effective capacitance.
