Bahwan Engineering Electronic Technician Interview Questions and Answers for Experienced

Q1. How to convert from A.C to D.c. Supply
Ans. 
A.C to D.C. conversion can be done using a rectifier circuit.
• A rectifier circuit can be used to convert A.C. to D.C.

• The rectifier circuit can be half-wave or full-wave.

• Half-wave rectifier only allows half of the A.C. wave to pass through, while full-wave rectifier allows the entire wave.

• The rectifier circuit can be made using diodes.

• The output of the rectifier circuit is not smooth and requires filtering using capacito...read more

Q2. What are the fundamentals of the power triangle?
Ans. 
The power triangle represents the relationship between real power, reactive power, and apparent power in an AC circuit.
• The power triangle is a visual representation of the relationship between real power (P), reactive power (Q), and apparent power (S) in an AC circuit.

• Real power (P) is the actual power consumed by the circuit and is measured in watts (W).

• Reactive power (Q) is the power that flows back and forth between...read more
