In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
Capacitors an electrical or electronic component that stores electric charges. Basically, a capacitor consists of 2 parallel plates made up of conducting materials, and a dielectric material (air, mica, paper, plastic, etc.) placed between them as shown in the figure. The specifications of capacitors are: 1. Capacitance Value
The capacitor is a component which has the ability or “capacity” to store energy in the form of an electrical charge producing a potential difference (Static Voltage) across its plates, much like a small rechargeable battery.
A capacitor consists of two terminals, it stores electrical power or energy in the shape of the electrical field. There are many types of capacitor but all do the same job storing of charge, all of these has two conductive plates which have a dielectric material in between them.
The property of a capacitor to store charge on its plates in the form of an electrostatic field is called the Capacitance of the capacitor. Not only that, but capacitance is also the property of a capacitor which resists the change of voltage across it.
A capacitor consists of two-terminal, it stores electrical power or energy in shape of an electrical field. As we discussed above capacitor has dielectric material among the electric plates this dielectric material do not allow direct current to pass instead it stores voltage in the shape of charge across plates of a capacitor.
