An ac generator supplies a peak (not rms) voltage of 150 V at 60.0 Hz. The generator is connected in series with a 35-mH inductor, a 45-µF capacitor and an 85-$\varOmega$ resistor.
-What is the power factor for this circuit?
A)0.47
B)0.54
C)0.64
D)0.88
E)28.3

Question

Quizplus · Accepted Answer

The power factor is calculated as the cosine of the phase angle, which is determined by the impedance of the circuit. The impedance is affected by the inductive reactance, capacitive reactance, and resistance. After calculating these values and the phase angle, the power factor is found to be approximately 0.88.
