Question

In the given transistor circuit, the base current is $35\mu A$. the value of $R_b$ is -

• A. $100k\Omega$
• B. $200k\Omega$
• C. $300k\Omega$
• D. $400k\Omega$

Answer 1

Answer: (B)

$200k\Omega$

In the given loop, we can use KVL, and we can get-

$7-\left(35\mu A\right).R_b=0$

$R_b=\frac{7}{\left(35\times {10}^{-6}\right)}=200000\Omega =200\text{k}\Omega$
