  1. Question 1

    Q1. A 220 V AC power source is connected to a 10 Ω resistor through a 50 μF capacitor. What is the impedance of the circuit?

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

    Answer: 50 Ω

    Explanation: The impedance is given by Z = √(R^2 + Xc^2), so it's 50 Ω, not 100 Ω, 200 Ω, or 500 Ω.
