ELECTRICAL ENCYCLOPEDIA

Fundamentals for all Capacitor http://www.sofia.usra.edu   For all practical purposes, consider only the parallel-plate capacitor: two conductors or electrodes separated by a dielectric material of uniform thickness.  The conductors can be any material which will conduct electricity easily. The dielectric material must be a poor conductor – an insulator. History of Capacitor http://www.hkcapacitor.com   In October 1745, Ewald Georg von Kleist of Pomerania in Germany found that charge could be stored by connecting a generator by a wire to a volume of water in a hand-held glass jar. Von Kleist's hand and the water acted as conductors and the jar as a dielectric. Von Kleist found that after removing the generator, touching the wire resulted in a spark. In a letter describing the experiment, he said "I would not take a second shock for the kingdom of France." The following year, the Dutch physicist Pieter van Musschenbroek invented a similar capacitor, which was named ...
