In an AC. circuit, a low value of kVAR compared with kW indicates_________?
Correct answer: B. high power factor
- A. low efficiency
- B. high power factor
- C. unity power factor
- D. maximum load current
Explanation
Since kVAR/kW = tanφ, a small reactive-power component compared with real power means a small phase angle and hence a high power factor. It does not necessarily mean unity power factor.
