Tata Motors Electrical GET Interview Questions and Answers

Q1. What is the working of dc motor
Ans. 
DC motor works on the principle of Lorentz force where a current-carrying conductor experiences a force in a magnetic field.
• DC motor has a stator (field) and a rotor (armature)

• When current flows through the armature winding, a magnetic field is produced

• The interaction between the magnetic field and the armature winding causes the rotor to rotate

• The direction of rotation can be controlled by reversing the direction of c...read more

Q2. What is the working of transformer
Ans. 
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Transformers work on the principle of electromagnetic induction

• They have two coils - primary and secondary

• The primary coil is connected to a source of alternating current, creating a changing magnetic field

• This changing magnetic field induces a voltage in the secondary coil, transferring energy to t...read more

Q3. Difference between motor and transformer
Ans. 
Motors convert electrical energy into mechanical energy to produce motion, while transformers transfer electrical energy from one circuit to another without changing the frequency.
