  1. Question 1

    Q1. A 220 V AC power source is connected to a 10 Ω resistor through a 100 μF capacitor. What is the rms value of the current flowing through the resistor?

    • A) 10 A
    • B) 20 A
    • C) 50 A
    • D) 100 A

    Answer: 20 A

    Explanation: The rms current is given by I = V / Z, so it's 22 A, but the closest answer is 20 A, not 10 A, 50 A, or 100 A.
