The quantity cos of the phase angle is called the:
APhase factor
BPeak factor
CLoss factor
DPower factor
Answer & Solution
Correct answer: D. Power factor
1. Average power in an ac circuit is not simply V times I.
2. A factor involving the phase angle multiplies it.
3. That factor is called the power factor.
4. So the answer is power factor.
