They consist of two conductive plates, known as electrodes, separated by an insulating material called a dielectric. When a voltage is applied, an electric field develops across the dielectric, causing the capacitor to store energy in the form of an electrostatic charge.
They have moving and fixed plates to determine the capacitance and are generally used in circuit of Transmitters and Receivers, Transistor Radios etc. The main function of a capacitor is to store electric energy in an electric field and release this energy to the circuit as and when required.
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.
In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric.
Therefore, capacitors play the three following important roles in an electronic circuit. Capacitors can charge and discharge because of the structure. Featured by the electric charge and discharge, capacitors also can be used as a power supply. Camera flashes utilize this feature of capacitors.
