MSBTE Practical Viva/Oral Questions and Answers

Here are Some Basic Practical Viva/Oral Questions with Simple Answers for MSBTE External VIVA/Oral Question and Answers K Scheme Electrical Engineering 3rd Semester from MSBTE 313015 Electrical Material and Wiring Practice Manual Answers or MSBTE 313015 EMWP Lab Manual Answers:

1.     What is the purpose of electrical wiring?
Electrical wiring provides a safe and reliable path for current flow to operate electrical devices.

2.     Define conductor.
A conductor is a material that allows the easy flow of electric current, such as copper or aluminum.

3.     What is an insulator?
An insulator resists the flow of current and is used for safety, e.g., rubber, glass, PVC.

4.     Why is copper used in wiring?
Copper has high conductivity, flexibility, and durability, making it ideal for wiring.

5.     What is the function of earthing?
Earthing provides a low-resistance path to discharge fault current safely to the ground.

6.     What is the difference between CTS and conduit wiring?
CTS wiring is surface wiring using cables, while conduit wiring uses protective pipes for wires.

7.     What is a fuse?
A fuse is a protective device that melts and breaks the circuit when current exceeds a safe limit.

8.     What is MCB?
Miniature Circuit Breaker (MCB) automatically trips to protect circuits from overloads or short circuits.

9.     What is ELCB?
Earth Leakage Circuit Breaker detects leakage current and disconnects supply to prevent shock hazards.

10.  What is the difference between one-way and two-way switch?
One-way switch controls a load from one location, while two-way switch controls from two locations.

11.  What is staircase wiring?
Staircase wiring allows controlling one lamp from two different locations, commonly used in stairs.

12.  What is insulation resistance?
The resistance offered by insulation material to current leakage is called insulation resistance.

13.  What is the purpose of megger?
A megger measures insulation resistance of cables and installations.

14.  What is the function of distribution board?
It distributes electrical supply to various circuits with protection devices like MCBs.

15.  What is the importance of earthing resistance?
Low earthing resistance ensures safety and proper dissipation of fault current.

16.  What is loop-in wiring system?
A method where supply is looped at each switch and socket for easy extension.

17.  What is the purpose of casing and capping wiring?
It provides mechanical protection and neat appearance for wiring.

18.  What are the types of electrical wiring?
CTS wiring, conduit wiring, casing-capping wiring, batten wiring.

19.  What is the function of switchgear?
Switchgear controls, protects, and isolates electrical circuits.

20.  What is polarity in wiring?
Polarity ensures correct connection of live and neutral wires for safety.

21.  Why is aluminum sometimes used instead of copper?
Aluminum is cheaper and lighter, though less conductive than copper.

22.  What is the function of neutral wire?
Neutral completes the circuit by carrying current back to the source.

23.  What is a short circuit?
Direct connection of live and neutral wires causing excessive current flow.

24.  What is the function of load wire?
Load wire supplies power to electrical appliances.

25.  Why is PVC insulation used?
PVC is durable, heat-resistant, and provides good insulation.

26.  What is the standard color code of live, neutral, and earth wires in India?
Live – Red/Brown, Neutral – Black/Blue, Earth – Green.

27.  What is the importance of safety devices in wiring?
They protect humans and equipment from shocks and fire hazards.

28.  What is a three-pin socket?
A socket with live, neutral, and earth connections for safe appliance operation.

29.  Why is proper wire size important?
Correct wire size prevents overheating, voltage drop, and power loss.

30.  What is the role of wiring practice in electrical engineering?
It builds practical skills for designing and maintaining safe electrical installations.
