Electrical Engineering Interview Questions and Answers
Question - 11 : - Explain RLC Circuit?
Answer - 11 : -
An RLC circuit carries out an electrical circuit consisting of a resistor (R) and the inductor (L) and a capacitor (C), linked in parallel. This circuit is known as a second-order circuit as any electrical energy or current in the circuit can be described by a next order discrepancy equation.
Question - 12 : - What are transistors comprised of?
Answer - 12 : -
Transistors are comprised of numerous combinations of n-type and p-type semiconductors.
Question - 13 : - What happens if the series current double?
Answer - 13 : -
If the series current gets double, then, the confrontation is halved.
Question - 14 : - What is a Zener diode?
Answer - 14 : -
Zener diode is a kind of semiconductor diode that permits existing to flow in the conflicting direction when uncovered to sufficient voltage.
Question - 15 : - What does a string of resistors in a series will do?
Answer - 15 : -
When a string of resistors in a sequence will split the source voltage into the amount to their values.
Question - 16 : - What is the role of the transistor in Circuit?
Answer - 16 : -
Transistor has the aptitude to intensify the current, due to the reason that output authority can be senior to the input power.
Question - 17 : - What are the types of semiconductors?
Answer - 17 : -
There are two kinds of semiconductors intrinsic and extrinsic. In extrinsic semiconductors, you will contain N-type semiconductors and P-type semiconductors.
Question - 18 : - What happens when two positively charged materials are placed together?
Answer - 18 : -
When two positively electric materials place jointly, it will repel.
Question - 19 : - What is automatic voltage regulator?
Answer - 19 : -
AVR is a contraction for Automatic Voltage Regulator. It is a central part of Synchronous Generators; it controls the production voltage of the originator by controlling its excitation current. Thus it can direct the Reactive productivity Power of the Generator.
Question - 20 : - Define Sf6 circuit breaker?
Answer - 20 : -
SF6 is Sulpher hexa Flouride gas. If this gas is used as arc quenching average in a Circuit breaker means SF6 CB.
