    A transistor has an \[\alpha =0.95\] it has charge in emitter current of \[100\,\,milli\] ampere, then the charge in collector current is

    A) \[95\,\,mA\]                     

    B) \[99.05\,\,mA\]

    C) \[00.95\,\,mA\]               

    D) \[100\,\,mA\]

    Correct Answer: A

    Solution :

    Here:\[\alpha =0.95\] So,\[\frac{\Delta {{I}_{C}}}{\Delta {{I}_{E}}}=0.95\]But\[\Delta {{I}_{E}}=100\,\,mA\] \[\Delta {{I}_{C}}=0.95\times \Delta {{I}_{E}}\] \[=0.95\times 100=95\,\,mA\]
