    Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:

    A transistor is used in common emitter mode as an amplifier. Then: (1) the base-emitter junction is forward biased (2) the base-emitter junction is reverse biased (3) the input signal is connected in series with the voltage  applied  to  bias  the base-collector junction (4) the input signal is connected in series with the voltage applied to the base-emitter junction

    A)  1 and 2 are correct

    B)  2 and 3 are correct

    C)  1 and 4 are correct

    D)  1, 2 and 3 are correct

    Correct Answer: C

    Solution :

                     While using a transistor as a common-emitter amplifier, the emitter-base junction is forward biased and the signal to be amplified is connected in emitter-base junction.
