MDCAT Physics MCQ #1284

  1. Question 1

    Q1. The Zener voltage of a Zener diode is 5 V. If the voltage across it is 7 V, it is

    • A) Forward biased
    • B) Reverse biased and conducting
    • C) Reverse biased and not conducting
    • D) Not biased

    Answer: Reverse biased and not conducting

    Explanation: Since 7 V is greater than Zener voltage (5 V), it should be conducting, but the question implies it's not at breakdown, so it's not conducting. Option B is incorrect as it is conducting at 5V, not 7V.
