$$\text { Figure } 12

Question

$$\text { Figure } 12 < 2$$
-What change Would increase the power factor in Figure 12-2?
A) increasing the value of the resistor 
B) decreasing the source voltage 
C) decreasing the value of the resistor 
D) increasing the source voltage

Quizplus · Accepted Answer

The power factor can be improved by reducing the phase angle between the voltage and current. This can be achieved by decreasing the value of the resistor, which will decrease the amount of reactive power flowing through the circuit and therefore reduce the phase angle. Increasing the source voltage or the value of the resistor would increase the reactive power and worsen the power factor. Decreasing the source voltage would not necessarily have a significant impact on the power factor.
