A capacitor(originally Known as condenser ) is an electronic passive device which has the ability to store energy in the form of  electric charge that creates potential difference which is static voltage. 

The capacitor consists of two parallel metallic (conductive)  plate which are not connected together and separated by an insulating material or air. This insulating material is known as dielectric.

Unlike resistor capacitor does not dissipate energy , it stores energy.

History of Capacitors

In October 1745, Ewald George von Kleist of Pomerania in Germany found that charge could be stored by connecting a high-voltage electrostatic generator by a wire to a volume of water in a hand-held glass jar. Von Kleist’s hand and the water acted as conductors, and the jar as a dielectric. Von Kleist found that touching the wire resulted in a powerful spark. The following year, the Dutch physicist Pieter van Musschenbroek invented a similar capacitor, which was named the Leyden jar.
