A) \[55\Omega \]
B) \[110\Omega \]
C) \[220\Omega \]
D) \[550\Omega \]
Correct Answer: B
Solution :
[b] (i) r is not there. |
\[I=9\times 60\mu A\] |
\[\frac{6}{11000+G}=540\times {{10}^{-6}}\] |
\[G=\frac{1000}{9}\] |
(ii) \[G=\frac{RS}{R-S}\] |
\[\frac{1000}{9}=\frac{11000S}{11000-S}\] |
This gives S = 110 |
