A capacitor is an electronic component to store electric charge. It is a passive electronic component that can store energy in the electric field between a pair of conductors called “Plates”. In simple words, we can say that a capacitor is a component to store and release electricity, generally as the result of a chemical action.
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.
The formation of double layers is exploited in every electrochemical capacitor to store electrical energy. Every capacitor has two electrodes, mechanically separated by a separator. These are electrically connected via the electrolyte, a mixture of positive and negative ions dissolved in a solvent such as water.
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.
When a voltage is applied to the capacitor, two layers of polarized ions are generated at the electrode interfaces. One layer is within the solid electrode (at the surfaces of crystal grains from which it is made that are in contact with the electrolyte).
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. It also allows to pass only AC Current and NOT DC Current. The formula for total capacitance in a parallel circuit is: CT=C1+C2…+Cn.
