  1. Question 1

    Q1. A coil is connected to a battery. The current in the coil is

    • A) maximum at t = 0
    • B) maximum at t = ∞
    • C) minimum at t = 0
    • D) constant for all t

    Answer: maximum at t = ∞

    Explanation: In an L-R circuit, current grows exponentially and becomes maximum at t = ∞.
