    For the transistor circuit shown below, if \[\beta =100,\]voltage drop between emitter and base is 0.7 V then value of \[{{V}_{CE}}\]will be

    A)  10 V                           

    B)  5 V

    C)  13V                            

    D)  0 V

    Correct Answer: C

    Solution :

    Base current\[={{i}_{b}}=\frac{5-0.7}{8.6}=0.5\,mA\Rightarrow \] Now,    \[{{I}_{c}}=\beta {{I}_{b}}=100\times 0.5\,mA\] By using \[{{V}_{CE}}={{V}_{CC}}-{{I}_{C}}{{R}_{L}}=18-50\times {{10}^{-3}}\times 100=13V.\] Hence, the correction option is .
