The energy Uof a capacitor that has charge Qon it and voltage V across it, is then the sum of such increments. In the limit of innitesimal increments, this sum converts into an integral. By using the denition of capacitance C= Q=V, we can write the expression for potential energy Uin three equivalent ways as shown on the slide.
The work done in charging a capacitor to a potential V is stored as potential energy in the capacitor. Letting one plate be earthed, the other plate is charged, and this work is the necessary work to charge the capacitor, making it the potential energy of the capacitor.
It depends on the amount of electrical charge on the plates and on the potential difference between the plates. The energy stored in a capacitor network is the sum of the energies stored on individual capacitors in the network. It can be computed as the energy stored in the equivalent capacitor of the network.
The total work W needed to charge a capacitor is the electrical potential energy U C U C stored in it, or U C = W U C = W. When the charge is expressed in coulombs, potential is expressed in volts, and the capacitance is expressed in farads, this relation gives the energy in joules.
The energy U C U C 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.
