The answer lies in what is called the "electric field." Imagine a capacitor at rest with no power going to either end. Each conductor would have the same charges in balance, and there would be no flow between or away from the plates. This capacitor is at rest and has no effective energy storage.

The energy stored in a capacitor is nothing but the electric potential energy and is related to the voltage and charge on the capacitor. If the capacitance of a conductor is C, then it is initially uncharged and it acquires a potential difference V when connected to a battery. If q is the charge on the plate at that time, then
It shows that the energy stored within a capacitor is proportional to the product of its capacitance and the squared value of the voltage across the capacitor. ( r ). E ( r ) dv A coaxial capacitor consists of two concentric, conducting, cylindrical surfaces, one of radius a and another of radius b.
The work done is equal to the product of the potential and charge. Hence, W = Vq If the battery delivers a small amount of charge dQ at a constant potential V, then the work done is Now, the total work done in delivering a charge of an amount q to the capacitor is given by Therefore the energy stored in a capacitor is given by Substituting
The energy in an ideal capacitor stays between the capacitor's plates even after being disconnected from the circuit. Conversely, storage cells conserve energy in the form of chemical energy, which, when connected to a circuit, converts into electrical energy for use.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
The merits and demerits of energy storage capacitors are compared with the other energy storage units. The basic need of an energy storage system is to charge as quickly as possible, store maximum energy, and discharge as per the load demand.

To begin with, I assume that the capacitor C is holding a charge Q, which means I can measure a voltage V across it. Then if I apply a bit of energy δW to the system I can persuade a small amount of extra charge δQ to move onto the capacitor. So I can write an equation in terms of Q.. Then I can use integration to add up all the little δWs (and they''re all slightly different) to …
