Imperial Electric Company Divisional Incharge Interview Questions and Answers

Current refers to the flow of electric charge in a circuit or the present time.

• Current is measured in Amperes (A)

• There are two types of current - direct current (DC) and alternating current (AC)

• In a circuit, current flows from the positive terminal of the voltage source to the negative terminal

• Current can be calculated using Ohm's Law: I = V/R, where I is current, V is voltage, and R is resistance

Transformers are rated in KVA because it represents the apparent power capacity of the transformer, taking into account both the voltage and current.

• KVA takes into account both the voltage and current, providing a more accurate representation of the transformer's capacity

• KVA is a unit of apparent power, which is the combination of real power (KW) and reactive power (KVAR)

• KVA rating helps in determining the maximum load...read more
