engineering physics MCQ #1233

  1. Question 1

    Q1. The time constant of an L-R circuit is 2 s. If the inductance is 1 H, resistance is

    • A) 0.5 ohm
    • B) 1 ohm
    • C) 2 ohm
    • D) 4 ohm

    Answer: 0.5 ohm

    Explanation: Time constant = L/R, hence R = L / time constant = 1 / 2 = 0.5 ohm.
