  1. Question 1

    Q1. The voltage across the resistor in a series LCR circuit is 100 V. If the supply voltage is 200 V, find the power factor.

    • A) 0.5
    • B) 1
    • C) 0.707
    • D) 0.866

    Answer: 0.5

    Explanation: Power factor = V_R / V = 100 / 200 = 0.5, where V_R is the voltage across the resistor and V is the supply voltage.
