All capacitors are formed with the same basic structure. Two parallel metal electrode plates are separated by a non-conductive material called the dielectric. When a voltage exists between these conductive parallel plates, an electric field is present in the dielectric. This field stores energy and produces a mechanical force between the plates.
In capacitors, the dielectric medium or material block the flow of charge carriers (especially electrons) between the conductive plates. As a result, the electric charges that try to move from one plate to another plate will be trapped within the plate because of the strong resistance from the dielectric.
The construction of capacitor is very simple. A capacitor is made of two electrically conductive plates placed close to each other, but they do not touch each other. These conductive plates are normally made of materials such as aluminum, brass, or copper. The conductive plates of a capacitor is separated by a small distance.
The circuit symbol of a basic capacitor is shown in the below figure. The capacitor symbol is represented by drawing two parallel lines close to each other, but not touching. It consists of two terminals. These terminals are used to connect in the circuit. The ability of a capacitor to store electric charge is called capacitance.
We find capacitors in televisions, computers, and all electronic circuits. A capacitor is an electronic device that stores electric charge or electricity when voltage is applied and releases stored electric charge whenever required. Capacitor acts as a small battery that charges and discharges rapidly.
A capacitor is usually made up of two conductive electrodes in which an insulating material called dielectric separates them as shown in (Fig. 9.6). Applied voltage causes electric charge to be gathered on the surface of the electrodes which are isolated by the dielectric layer, hence, generating an electric field.
