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 :

  1. Storing electric potential energy such as batteries.
  2. Filtering out unwanted frequency signals
  3. Delaying voltage changes when coupled with resistors.
  4. Used as a sensing device.
  5. Used in the audio system of the vehicle.
  6. 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.
