Aptiv 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
