    In n-p-n transistor, the collector current is 10mA.    If 90% of electrons emitted reach the collector, then:

    A)  emitter current will be \[9\,mA\]

    B)  emitter current will be \[11.1\,mA\]

    C)  base current will be \[0.1\,mA\]

    D)  base current will be \[0.01\,mA\]

    Correct Answer: B

    Solution :

    Here        \[{{I}_{C}}=0.9\,|E\] \[\Rightarrow \]               \[1E=\frac{10}{0.9}=11.1mA\]
