  1. Question 1

    Q1. In an AC circuit, the true power is 800 W and the apparent power is 1000 VA. What is the power factor?

    • A) 0.4
    • B) 0.6
    • C) 0.8
    • D) 1

    Answer: 0.8

    Explanation: Power factor = True Power / Apparent Power = 800 W / 1000 VA = 0.8. Option A is incorrect because it is less than the correct value.
