An induction motor works on the principle of electromagnetic induction to convert electrical energy into mechanical energy.

• Induction motor has a stator and a rotor.

• When AC current is passed through the stator windings, a rotating magnetic field is produced.

• The rotating magnetic field induces currents in the rotor windings, causing it to rotate.

• The rotor speed is slightly less than the speed of the rotating magnetic field, known as slip.

• Commonly used in appliances, pumps, fans...read more

Current is the flow of electric charge through a conductor.

• Current is measured in amperes (A).

• It is caused by the movement of electrons or other charged particles.

• Current can be either direct current (DC) or alternating current (AC).

• In a DC circuit, current flows in one direction, while in an AC circuit, it periodically changes direction.

• Examples of current include the flow of electricity in a wire or the movement of electrons in a battery.

AC and DC are two types of electrical current. AC changes direction periodically, while DC flows in one direction.

• AC stands for alternating current, while DC stands for direct current.

• AC changes direction periodically, typically in a sinusoidal waveform.

• DC flows in one direction continuously.

• AC is used for power transmission over long distances.

• DC is commonly used in batteries and electronic devices.

• AC can be easily converted to DC using rectifiers.

• DC can be converted to AC u...read more
