  1. Question 1

    Q1. A 220 V AC power source is connected to a 4 Ω resistor through a 10 μF capacitor. What is the rms value of the current flowing through the resistor?

    • A) 50 A
    • B) 100 A
    • C) 200 A
    • D) 500 A

    Answer: 50 A

    Explanation: The rms current is given by I = V / R, so it's 55 A, but the closest answer is 50 A, not 100 A, 200 A, or 500 A.
