What is a generator? Generator – a machine that changes mechanical energy to electrical energy Usually use moving magnets to create currents in coils of wire. www.assignmentpoint.com

There are two types of generators, one is ac generator and other is DC generator. Whatever may be the types of generators, it always converts mechanical power to electrical power. An AC generator produces alternating power. A DC generator produces direct power. Both of these generators produce electrical power, based on same fundamental principle of Faraday's law of electromagnetic induction. www.assignmentpoint.com

With the help of a generator, the electrons can transmit electric energy from one point to another. The difference in the number of electrons and the pressure that the generator applies is what creates the different electric currents. The generator spins at a certain number of rotations per minute. The number of electrons that move is measured in amps. The pressure is measured in volts. In the United States, the electric current in the power outlets is 120 volts. www.assignmentpoint.com

The operation of electric generators is based on the process called electromagnetic induction: whenever a conductor moves relative to a magnetic field, electromotive force (emf) is induced in this conductor. Particularly, if a magnet is spinning inside a coil, a periodic AC voltage is induced between its terminals.  www.assignmentpoint.com
