  1. Question 1

    Q1. The power factor of an AC circuit is 0.8. If the true power is 800 W, what is the apparent power?

    • A) 640 W
    • B) 800 W
    • C) 1000 W
    • D) 1200 W

    Answer: 1000 W

    Explanation: Power factor = True Power / Apparent Power. So, Apparent Power = True Power / Power Factor = 800 W / 0.8 = 1000 W. Option A is incorrect because it results from multiplying instead of dividing.
