Capacitor
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..
5.20: Real Capacitors
There is a type of capacitor known as an electrolytic capacitor. The two "plates" are strips of aluminium foil separated by a conducting paste, or electrolyte. One of the foils is covered by an extremely thin layer of aluminium oxide, which has been electrolytically deposited, and it is this layer than forms the dielectric medium, not the paste that separates the two foils.

A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the current.
