  1. Question 1

    Q1. An inductor coil has an inductance of 10 mH and a resistance of 5 Ω. It is connected to a 10 V DC source. The current after a long time is

    • A) 0 A
    • B) 1 A
    • C) 2 A
    • D) ∞

    Answer: 2 A

    Explanation: In DC, inductor behaves like a wire. So, I = V/R = 10/5 = 2 A
