Electrical Help at Your Fingertips

Alternating current can be dangerous if not used properly. For example, touching a live wire carrying AC can result in electrocution. AC can cause interference in electronic devices, which can lead to data loss or corruption. 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.

Unlike an asynchronous AC motor, a synchronous AC motor rotates at the same speed as the frequency of the AC power supply. In order to achieve this, the synchronous AC motor must be synchronized with the power supply using a feedback system. 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..
