The Leyden Jar is an early form of what?
Leyden jar decreasing in length, can be obtained at intervals. This effect is caused by dielectric absorption. In 1747–1748, Benjamin Franklin experimented with charging Leyden jars in series. Leyden jar A Leyden jar (or Leiden jar) stores a high-voltage electric charge (from an external source) between electrical conductors 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 the capacitor
Leyden jar van Musschenbroek of Leiden (Leyden) in 1745–1746. The invention was named after 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 electrostatics. The Leyden jar was the first means of accumulating and preserving electric charge in large quantities that could be discharged at the experimenter's will, thus overcoming a significant limit to early research into electrical conduction. Leyden jars are still used in education to demonstrate the principles of electrostatics. The Ancient Greeks already knew that pieces of amber could attract lightweight particles after
