Leyden jar
Leyden jarn. An early form of capacitor consisting of a glass jar lined inside and out with tinfoil and having a conducting rod connected to the inner foil lining and passing out of the jar through an insulated stopper.
[After Leyden (Leiden).]Leyden jar n (Electrical Engineering) physics an early type of capacitor consisting of a glass jar with the lower part of the inside and outside coated with tin foil [C18: first made in Leiden]Ley′den jar`
n. a device for storing electric charge, consisting essentially of a metal rod in a glass jar lined inside and outside with tinfoil. [1815–25; so called because invented in Leyden] Ley·den jar (līd′n) 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.Thesaurus| Noun | 1. |  Leyden jar - an electrostatic capacitor of historical interestLeiden jarcapacitor, condenser, electrical condenser, capacitance - an electrical device characterized by its capacity to store an electric charge |

It consists of a narrow-necked glass jar coated over part of its inner and outer surfaces with conductive metal foil; a conducting rod or wire passes through an insulating stopper in the neck of the jar and contacts the inner foil layer, which is separated from the outer layer by the glass wall. By modern standards, the Leyden jar is cumbersome and inefficient. It is rarely used except in laboratory demonstrations of capacitance.Leyden jar[′līd·ən ‚jär] (electricity) An early type of capacitor, consisting simply of metal foil sheets on the inner and outer surfaces of a glass jar.
