Question

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

• A. $300KW$
• B. $450KW$
• C. $257KW$
• D. $500KW$

Answer 1

The correct option is C $257KW$

$\begin{array}{c}{V}_b=i_b{R}_b\\ \Rightarrow R_b=\frac{9}{35\times {10}^{-6}}=257KW\end{array}$

Hence,

option $\left(C\right)$ is correct answer.
