What is a Capacitor? Capacitor (also known as condenser) is a two metal plates device separated by an insulating medium such as foil, laminated paper, air etc. It stores the energy in the form of electrostatic filed and released to the circuit when needed in case of AC. It storage ability is measured in Farad "F" and "µF" or "nF" units are used for small capacitors.
