  1. Question 1

    Q1. The power factor of an AC circuit is 0.5. If the true power is 100 W, what is the apparent power?

    • A) 200 VA
    • B) 50 VA
    • C) 100 VA
    • D) 400 VA

    Answer: 200 VA

    Explanation: Power factor = True power / Apparent power. So, Apparent power = True power / Power factor = 100 / 0.5 = 200 VA.
