Leyden Jar

A Leyden jar, or Leiden jar, is a device that "stores" static electricity? between two electrodes on the inside and outside of a glass jar. It was the original form of a capacitor (originally known as a "condenser").

It was invented independently by German cleric Ewald Georg von Kleist? on 11 October 1745 and by Dutch scientist Pieter van Musschenbroek? of Leiden (Leyden) in 1745–1746. The invention was named for the city.

The Leyden jar was used to conduct many early experiments in electricity, and its discovery was of fundamental importance in the study of electricity. Previously, researchers had to resort to insulated conductors of large dimensions to store a charge. The Leyden jar provided a much more compact alternative. Wikipedia, Leyden Jar (external link)
