An inductor is one of important device in electrical circuits. To study response of it in pure form, inductor 240 mH is connected to AC source of maximum voltage 280 V, with a frequency of 120 Hz. Predict the rms current passing through the circuit. Can you predict the change in rms current if the frequency is increased to 5 kHz? Are there any similar properties for a transformer compared with inductor? Is it possible to operate inductor with DC source? Justify your answer.

Single Phase Induction Motor

The single-phase induction motor or engine consists of a single rotating phase in the stator and a rotating cage in the rotor. When phase one supply is connected to the stator winding, a magnetic field is generated. In the pulsating field, the rotor does not rotate due to inertia. So, a single-phase import motor does not start and requires some initial methods.
