    The current gain of a transistor in common base mode is 0.995. The current gain of the same transistor in common emitter mode is

    A)  197                                       

    B)  201                       

    C)  198                       

    D)         202

    E)  199

    Correct Answer: E

    Solution :

    \[\beta =\frac{\alpha }{1-\alpha }=\frac{0.995}{1-0.995}\] \[=\frac{0.995}{0.005}=199\]
