    In circuit shown the base current is \[30\mu A\] and voltage drop accross terminal B & E is \[0.7\text{ }V\] then value of \[{{R}_{i}}\] is :-

    A)  \[3\,k\Omega \]                              

    B)  \[30\,k\Omega \]

    C)  \[300\,k\Omega \]        

    D)  \[3\times {{10}^{4}}\,k\Omega \]

    Correct Answer: C

    Solution :

    Voltage across R is \[9.7-0.7\]and current in \[30\mu A\] so \[R=\frac{9}{30}=300k\Omega \]
