  1. Question 1

    Q1. The drift velocity of electrons is 0.1 mm/s when the current is 1 A. If the current is doubled, the drift velocity will be?

    • A) 0.2 mm/s
    • B) 0.1 mm/s
    • C) 0.05 mm/s
    • D) 0.4 mm/s

    Answer: 0.2 mm/s

    Explanation: Drift velocity is directly proportional to current. So, if current doubles, drift velocity doubles.
