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..

Ohm’s law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. In other words, the higher the voltage, the higher the current. 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 induction motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.
