    In a transistor circuit shown here the base current is 35 mA. The value of the resistor Rb is

    A)            123.5 kW

    B)            257 kW

    C)            380.05 kW

    D)            None of these

    Correct Answer: B

    Solution :

               \[{{V}_{b}}={{i}_{b}}{{R}_{b}}\Rightarrow {{R}_{b}}=\frac{9}{35\times {{10}^{-6}}}\]=257 kW.
