Principle of transformer & induction machines.

Question

Accepted Answer

The principle of transformer is based on electromagnetic induction, where a changing magnetic field induces a voltage in a coil. Induction machines work on the principle of electromagnetic induction to convert electrical energy into mechanical energy.

Transformer operates on the principle of mutual induction, where two or more coils are wound on a common magnetic core.
When an alternating current flows through the primary coil, it creates a changing magnetic field, which induces a voltage in the secondary coil.
The voltage transformation ratio of a transformer is determined by the ratio of the number of turns in the primary and secondary coils.
Induction machines, such as induction motors and generators, work on the principle of electromagnetic induction.
In an induction motor, a rotating magnetic field is created by the stator winding, which induces currents in the rotor winding, resulting in the generation of torque.
In an induction generator, mechanical energy is used to rotate the rotor, which induces a voltage in the stator winding, generating electrical power.
