JEE Main & Advanced Physics Semiconducting Devices Question Bank Assertion and Reason

  • question_answer
    Assertion             :       In transistor common emitter mode as an amplifier is preferred over common base mode. Reason                 :       In common emitter mode the input signal is connected in series with the voltage applied to the base emitter function.

    A)             If both assertion and reason are true and the reason is the correct explanation of the assertion.

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.

    C)             If assertion is true but reason is false.

    D)             If the assertion and reason both are false.

    E)             If assertion is false but reason is true.

    Correct Answer: B

    Solution :

                Common emitter is prepared over common base because all the current, voltage and power gain of common emitter amplifier is much more than the gains of common base amplifier.
