  1. Question 1

    Q1. A 1000 Ω resistor is connected in series with a 1000 μH inductor and a 10 nF capacitor. If the capacitor is charged to 10 V, what is the instantaneous voltage across the inductor?

    • A) 10 V
    • B) 20 V
    • C) 30 V
    • D) 40 V

    Answer: 30 V

    Explanation: Using the inductor voltage formula, the instantaneous voltage is calculated from v_L = -L * di/dt, giving 30 V
