Capacitor
Passive two-terminal electronic component that stores electrical energy in an electric field
This article is about the electronic component. For the physical phenomenon, see Capacitance. For an overview of types, see Capacitor types.
"Capacitive" redirects here. For the term used when referring to touchscreens, see Capacitive sensing.
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,[1] a term still encountered in a few compound names, such as the condenser microphone. It is a passiveelectronic component with two terminals.
The utility of a capacitor depends on its capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed specifically to add capacitance to some part of the circuit.
The physical form and construction of practical capacitors vary widely and many types of capacitor are in common use. Most capacitors contain at least two electrical conductors, often in the form of metallic plates or surfaces separated by a dielectric medium. A conductor may be a foil, thin film, s

Leyden jar
Antique electrical device that stores a high-voltage electric charge
Early water-filled Leyden jar, consisting of a bottle with a metal spike through its stopper to make contact with the water
Later, more common type using metal foil, 1919
A Leyden jar (or Leiden jar, or archaically, Kleistian jar) is an electrical component that stores a high-voltage electric charge (from an external source) between electrical conductors on the inside and outside of a glass jar. It typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting vertically through the jar lid to make contact with the inner foil. It was the original form of the capacitor[1] (also called a condenser).[2]
Its invention was a discovery made independently by German cleric Ewald Georg von Kleist on 11 October 1745 and by Dutch scientist Pieter van Musschenbroek of Leiden (Leyden), Netherlands, in 1745–1746.[3]
The Leyden jar was used to conduct many early experiments in electricity, and its discovery was of fundamental importance in the study of electrostatics. It was the first means of accumulating and preserving electric charge in large quantities that could be discharged at the exp
