Kakatiya Cement Sugar & Industries Interview Questions and Answers

Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.

• Transformers have two coils of wire, known as the primary and secondary coils.

• When an alternating current flows through the primary coil, it creates a changing magnetic field.

• This changing magnetic field induces a voltage in the secondary coil, transferring electrical energy.

• The ratio of the number...read more

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 flows through the stator windings, it creates a rotating magnetic field

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

• The rotor always lags slightly behind the rotating magnetic field, creating torque

• Co...read more

Transformers are electrical devices that transfer electrical energy between two or more circuits through electromagnetic induction.

• There are two main types of transformers: step-up transformers and step-down transformers.

• Step-up transformers increase voltage levels, while step-down transformers decrease voltage levels.

• Transformers work on the principle of electromagnetic induction, where a changing magnetic field induc...read more
