The charges flow through the capacitor when it is supplied with electricity, but this flow is blocked by the insulator between the metal plates. Consequently, the charges are accumulated in one of the two metal plates, while the other plate is induced with an opposing charge.
A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates …
In the capacitance formula, C represents the capacitance of the capacitor, and varepsilon represents the permittivity of the material.

Example 5.1: Parallel-Plate Capacitor Consider two metallic plates of equal area A separated by a distance d, as shown in Figure 5.2.1 below. The top plate carries a charge +Q while the bottom plate carries a charge –Q. The charging of the plates can be accomplished by means of a battery which produces a potential difference.
A parallel plate capacitor is a device that uses two metal plates with the same surface area as electrodes. One plate is positive and the other is negative when a power source is applied. The plates are separated by a gap filled with a dielectric material, which doesn''t conduct electricity but can hold electrostatic charges without any energy loss.

In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…
