    The transfer ratio \[\beta \] of a transistor is 50. The input resistance of the transistor when used in the common emitter configuration is 1 kn. The peak value of the collector A.C. current for an A.C. input voltage of \[0.01\text{ }V\] peak is

    A)  \[100\,\mu A\]

    B)  \[0.01\,mA\]

    C)  \[0.25\,mA\]

    D)  \[500\,\mu A\]

    Correct Answer: D

    Solution :

    [d] \[{{i}_{c}}=\beta .\frac{{{V}_{s}}}{{{R}_{in}}}=50\times \frac{0.01}{1000}=500\times {{10}^{-6}}A\] \[=500\,\mu A\]
