= Generators and Alternators =

Generators and alternators are devices that turn mechanical energy, usually rotational, into electrical energy.They work by changing the magnetic flux through a coil of wire, which will generate a potential difference and associated current. They are similar to electric motors and motors can be used as generators in some cases. Generators are typically devices that produce DC while alternators produce AC although the terms many times are used interchangeably.
