definition

A capacitor is any electrical component that stores electric charge.

INVENTION
  • The Leyden jar was the world’s first device used for storing electric charge. It was first invented on 11 October, 1745 by the German physicist Ewald Georg von Kleist and called the “Kleistian jar”. Then in 1745-1746 it was once again independently invented by the Dutch scientist Pieter van Musschenbroek in the Dutch city of Leiden (Leyden) and due to successful marketing of the device, it was called the “Leyden jar”.
  • Before the invention of the electric generator, electricity was created by electrostatic generators such as a rotating glass ball touching a wire; charges from the glass ball flow through the wire to the metal electrode and into the water and glass. Glass is not a perfect insulator so some charge is stored in the glass. Van Musschenbroek held the glass jar in one hand and when he touched the metal electrode he felt a powerful shock; this was because his body was conducting the charges and when he touched the metal electrode he completed the “circuit”.
