The input of an A.C. circuit having power factor of 0.8 lagging is 40 kVA The power drawn by the circuit is__________?
Correct answer: C. 32 kW
- A. 12 kW
- B. 22 kW
- C. 32 kW
- D. 64 kW
Explanation
Real power is P = S cosφ, so P = 40 kVA × 0.8 = 32 kW. The lagging nature affects current phase, not this real-power multiplication.
