An alternator is a device that creates alternating current by transforming mechanical energy into electrical energy. Read more..

Rectifiers work by allowing only half of the AC cycle to pass through them. During the positive half-cycle, the rectifier allows electrons to flow from the negative terminal to the positive terminal. Read more..

Alternating current (AC) is an electric current that reverses direction periodically. This means that the voltage of an AC signal also reverses direction periodically.

The frequency of an AC signal is the number of times per second that the current or voltage reverses direction. Read more..

An AC motor works by using electromagnetism to convert electrical energy into mechanical energy. The alternating current creates a rotating magnetic field that interacts with the armature, or rotor, of the motor to create torque. Read more..
