What is another word for Leiden Jar?
Pronunciation: [lˈe͡ɪdən d͡ʒˈɑː] (IPA) 
A 'Leiden jar' is a type of capacitor that stores static electricity. Synonyms for this term include 'Leyden jar', 'Leyden phial' and 'Condenser jar'. The origins of the jar date back to the mid-eighteenth century, when the Dutch scientist, Pieter van Musschenbroek, first created them to help explore the properties of static electricity. The jars were made from an outer glass casing and an inner metal coating, separated by a layer of insulating material. Once charged, a Leyden jar could hold a significant amount of electrical energy. Today, these jars are still used in laboratory experiments to study the properties of electrical charge.
