Expert Solution
The capacitor is a device in which electrical energy can be stored. It is an arrangement of two-conductor generally carrying charges of equal magnitudes and opposite sign and separated by an insulating medium. The non-conductive region can either be an electric insulator or vacuum such as glass, paper, air or semi-conductor called as a dielectric.
Capacitor vary in shape and size, they have many important applications in electronics.
What are Capacitors Used :
- Storing electric potential energy such as batteries.
- Filtering out unwanted frequency signals
- Delaying voltage changes when coupled with resistors.
- Used as a sensing device.
- Used in the audio system of the vehicle.
- Used to separate AC and DC
The capacitor is a device in which electrical energy can be stored.
Storing electric potential energy such as batteries.
