Capacitive charge storage results from the physical separation of charges at the interface of an electrode. An electric capacitor consists of electrodes with an electrically insulating but polarizable dielectric between them.
A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up. When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates.
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.
Thus, the storage capacitance mainly depends on the size of the metal plates, distance between the plates, and the material type of the dielectric medium used. It can be noted that the energy being stored in a capacitor is directly proportional to the capacity and the square of the applied voltage across the terminals of the electrochemical cell.
In order to charge the capacitor to a charge Q, the total work required is W = ∫W (Q) 0 dW = ∫Q 0 q Cdq = 1 2Q2 C. Since the geometry of the capacitor has not been specified, this equation holds for any type of capacitor. The total work W needed to charge a capacitor is the electrical potential energy UC stored in it, or UC = W.
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 ).
