MDCAT Physics MCQ #486

  1. Question 1

    Q1. What happens to the drift velocity of electrons when the potential difference across a conductor is doubled?

    • A) It doubles
    • B) It halves
    • C) It remains the same
    • D) It becomes zero

    Answer: It doubles

    Explanation: Drift velocity is directly proportional to the electric field, hence doubling the potential difference doubles it. Option C is incorrect as drift velocity isn't constant.
