emergency generator power

An electrical generator is a device that produces electrical energy from a mechanical energy source using electromagnetic induction. The process is known as electricity generation.

Historic developments

Before the connection between magnetism and electricity was discovered, generators used electrostatic principles. generator home power. The Wimshurst machine used electrostatic induction or "influence". The Van de Graaff generator uses either of two mechanisms:

Electrostatic generators are inefficient and are useful only for scientific experiments requiring high voltages.

Faraday

In 1831-1832 Michael Faraday discovered that a potential difference is generated between the ends of an electrical conductor that moves perpendicular to a magnetic field. He also built the first electromagnetic generator called the Faraday disc, a type of homopolar generator, using a copper disc rotating between the poles of a horseshoe magnet. It produced a small direct current of electricity. CableOrganizercom is.
