Bhansali Engineering Polymers Assistant Electrical Engineer Interview Questions and Answers

Q1. What's the motor and working?
Ans. 
The motor is a device that converts electrical energy into mechanical energy to perform work.
• A motor consists of a rotor and a stator, with the rotor rotating inside the stator.

• Motors can be AC (alternating current) or DC (direct current) depending on the type of power source.

• Common types of motors include induction motors, synchronous motors, and brushed or brushless DC motors.

• Motors are used in various applications s...read more

Q2. Tell about transformer working principal,
Ans. 
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 between the two coils.
