Basic Electrical Questions

Electrical Engineering Interview questions:

1-What are the most commonly used semiconductor materials?

Silicon (Si) and germanium (Ge)

2 -What device that passes current in one direction only?

Diode

3- Can you name different types of flip-flops?

D, T, R-S, and J-K.

4 - What is the voltage gain or transfer function of amplifier?

Vout/Vin

5- What types domain of Laplace transforms? What behavior can Laplace transform predict how the system work?

Types domain of Laplace transforms is s-domain, Laplace transforms provide a method to find position, acceleration or voltage the system will have.

6-What is “pu” in EE?

Pu stands for per unit in power system. (pu = actual value/ base value)

7-What does quality factor depend on in resonance?

Quality factor q depends on frequency and bandwidth.

8-What is the other name for short circuit?

A fault.

9- Name power losess in rotating electrical machines.

Power losess in rotating electrical machines are Copper losses, core losses, mechanical losses and stray losses.
