[1815–25; so called because invented in Leyden]
An early device for storing electric charge. It consists of a glass jar with conductive metal foil covering most of the inner and outer surfaces (all except the top parts). A metal rod or wire, used to draw electric charge into the jar, touches the inner foil and then exits through an insulating stopper in the neck.
