  1. Question 1

    Q1. A 20 Hz AC circuit contains a 500 mH inductor and a 100 nF capacitor. What is the capacitive reactance?

    • A) 200 ohm
    • B) 400 ohm
    • C) 800 ohm
    • D) 1600 ohm

    Answer: 800 ohm

    Explanation: The correct answer is C because the capacitive reactance is inversely proportional to the frequency and capacitance.
