  • question_answer
    Assertion (A): Semiconductors do not obey Ohm's law.
    Reason (R): V-I characteristic of semiconductors is linear.

    A) Both A and R are true and R is the correct explanation of A

    B) Both A and R are true but R is NOT the correct explanation of A

    C) A is true but R is false

    D) A is false and R is true

    Correct Answer: C

    Solution :

    Option [c] is correct.
    Explanation: Semiconductors do not obey Ohm's law. So the assertion is true. V-I characteristic of semiconductor is non-linear.
    Hence the reason is false.
