Electrostatic machine is a high voltage static electricity generating device that was used by Benjamin Franklin for research, 1764. Experiments from it eventually lead to the invention of the lightning rod and new theories about electricity. An electrostatic generator, or electrostatic machine, is an electromechanical generator that produces static electricity, or electricity at high voltage and low continuous current. The knowledge of static electricity dates back to the earliest civilizations, but for millennia it remained a mystifying phenomenon often confused with magnetism. By the end of the 17th Century, researchers had developed practical means of generating electricity by friction, but the development of electrostatic machines did not begin in earnest until the 18th century, when they became fundamental instruments in the studies about the new science of electricity.
