? Top Electrical Engineering Interview Questions with Answers (2026)

1. What is Ohm’s Law?

? Sample Answer:

Ohm’s Law states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to resistance.
Formula: V = IR

? Tip:

Be ready to explain practical applications.

2. What is the difference between AC and DC?

? Sample Answer:

• AC (Alternating Current): Changes direction periodically (used in homes)
• DC (Direct Current): Flows in one direction (used in batteries)

3. What is a Transformer?

? Sample Answer:

A transformer is an electrical device used to increase or decrease voltage in an AC circuit using electromagnetic induction.

4. What are Kirchhoff’s Laws?

? Sample Answer:

• KCL (Kirchhoff’s Current Law): Sum of currents entering a node equals sum leaving
• KVL (Kirchhoff’s Voltage Law): Sum of voltages in a loop equals zero

5. What is Power Factor?

? Sample Answer:

Power factor is the ratio of real power to apparent power. It indicates efficiency of electrical systems.

6. What is the difference between MCB and MCCB?

? Sample Answer:

• MCB: Used for low current protection
• MCCB: Used for higher current and industrial applications

7. What is a Circuit Breaker?

? Sample Answer:

A circuit breaker is a safety device that automatically interrupts current flow during overload or short circuit.

8. What is Earthing?

? Sample Answer:

Earthing is the process of connecting electrical systems to the ground to prevent electric shock.

9. What is a Relay?

? Sample Answer:

A relay is an electrically operated switch used to control circuits.

10. What is a Generator?

? Sample Answer:

A generator converts mechanical energy into electrical energy using electromagnetic induction.

? Advanced Electrical Engineering Interview Questions

11. What is the difference between synchronous and asynchronous motors?

? Answer:

• Synchronous Motor: Runs at constant speed
• Asynchronous Motor: Speed varies with load

12. What is SCADA?

? Answer:

SCADA (Supervisory Control and Data Acquisition) is a system used for monitoring and controlling industrial processes.

13. What is Harmonics?

? Answer:

Harmonics are unwanted frequencies that distort electrical signals.

14. What is Load Flow Analysis?

? Answer:

It is the study of power flow in an electrical system to ensure efficient operation.

15. What is an Inverter?

? Answer:

An inverter converts DC to AC supply.
