B) product
C) ratio
D) dividend

Question

Quizplus · Accepted Answer

Power factor is defined as the ratio of true power (P) to apparent power (S). In an R-L series circuit, the true power is the power dissipated by the resistor and the reactive power is the power absorbed by the inductor. Therefore, the power factor is the ratio of the true power to the apparent power, which is the sum of the true power and the reactive power. Thus, the best choice is C, which states that power factor is a ratio.
