    In a common base configuration; (transistor circuit) \[{{I}_{E}}=1\]mA, \[{{I}_{c}}=\] 0.95mA. The value of base current is

    A)  1.95mA                               

    B)  0.05mA

    C)  1.05mA                               

    D)  0.95mA

    Correct Answer: B

    Solution :

    For a common base transistor \[{{I}_{E}}={{I}_{B}}+{{I}_{C}}\] \[1\,mA={{I}_{B}}+0.95mA\] \[{{I}_{B}}=0.05mA\]
