Afcons Infrastructure Technician Interview Questions and Answers

Q1. What is ohm's law
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.
• Ohm's law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit has a volt...read more

Q1. 1/Wat ht vcb worck For Ht use
Ans. 
The question is asking about how a VCB (Vacuum Circuit Breaker) works for high voltage (HT) applications.
• VCB is a type of circuit breaker that uses vacuum as the arc quenching medium.

• It is commonly used in high voltage applications to interrupt or isolate electrical circuits.

• When the VCB is closed, the contacts are in physical contact, allowing the current to flow.

• When the VCB is opened, the contacts are separated, cre...read more

Q1. Which is more deficult .AC&DC
Ans. 
AC and DC both have their own challenges, but AC is generally considered more difficult due to its changing voltage and frequency.
• AC involves constantly changing voltage and frequency, which can be more challenging to work with compared to the steady flow of DC.

• AC circuits require additional components like capacitors and inductors to manage voltage and current fluctuations.

• DC circuits are simpler to understand and tro...read more

Q1. What is CB operation and use?
Ans. 
CB operation and use refers to the operation and use of circuit breakers in electrical systems.
• CBs are used to protect electrical systems from overloads and short circuits.

• They work by interrupting the flow of current when a fault is detected.

• CBs can be manually or automatically operated.

• They come in different types, such as air, oil, vacuum, and SF6 CBs.

• CBs are commonly used in residential, commercial, and industrial
