Capacitor
A capacitor is a two-terminal passive device.Capacitor stores electrical energy in the form of electric charges. First capacitors are called as electric condenser. These capacitor consists of two parallel plates in which positive and negative charges stores. In between the two plates there will be a dielectric material like paper, ceramic and mica. When the electric energy is applicable capacitor get charged stores energy and power is switched off then the capacitor gets discharged. The amount of charges can be stored is given by capacitance. It is measured in the unit Farad. There are various types in capacitor. They are:
- Fixed capacitor
- Variable capacitor
- Polarized capacitor
