These alternators are rated in terms of the amperage they produce making alternators available in variety of power or strength of a current of electricity expressed and measured in amperes. Also, found on older vehicles are DC generator, instead of an alternator, and generator-to-alternator conversions have become popular among enthusiasts who drive vintage vehicles.

An alternator assembly contains by the following components - a rotating field winding called the rotor, a stationary induction winding called the stator, a diode assembly called the rectifier bridge, a control device called the voltage regulator, and two internal fans to promote air circulation.
