20 Technical Questions Asked To Electrical Engineers in SSB

The personal interview is always related to the personal topics of the candidate. But in direct entries, where the engineers are called for the interview, sometimes, technical questions related to the stream, are also asked by the IO to check the theoretical knowledge of the candidate. These are not too tough and deep as it is just to check the basic knowledge of the candidates. For electrical engineers, here are 20 questions which are asked by the IO.

  1. Why are AC devices used over DC devices?
  2. What is the difference between a generator and an alternator?
  3. What are the types of semiconductors?What is the major difference between Digital and Analog signals?
  1. What is rectifier and what are its type?
  2. What is knee voltage point?
  3. What is MARX Circuit and where is it used?
  4. What is the principle behind the working of an electric motor?
  5. What are the different types of Dc motors?
  6. Tell me what will happen in case I connect a lamp with two-phase?
  7. If I buy an air conditioner, it is mentioned that its capacity is 1 ton. What does it mean?
  8. Tell me the difference between a fuse and a circuit breaker.
  9. What type of losses are there in a transformer?
  10. What are the main function and basic difference between of an invertor and a UPS?
  11. Which type of motors are used in trains?
