LEYDEN JAR

LEYDEN JAR:

This is a device that “stores” static electricity between two electrodes on the inside and outside of a glass jar. A Leyden jar 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 a capacitor.

Specifications:

• For demonstration of the basic principle of capacitance and its use in storage of charge.
• Comprises an insulated plastic can along with a two metal conducting cans one inside the plastic vessel and the other outside, the dielectric plastic can providing complete insulation between the two metal cans.
• The inner can has a hook shaped metal rod terminating in a metal sphere at the top for charging / discharging the Leyden jar.
• The apparatus can be easily disassembled and once charged in assembled condition, retains its charge even after assembly and disassembly
