A) \[10\text{ k}\,\Omega \]
B) \[9.9\text{ }k\Omega \]
C) \[8.9\text{ }k\Omega \]
D) \[7.9\text{ }k\Omega \]
Correct Answer: B
Solution :
V = 10 volt When 1 mA current will be flowing \[\therefore 10=1\times {{10}^{3\text{ }}}\left( 100+{{R}_{0}} \right)\] \[\Rightarrow 10000100=9900\text{ }\Omega ={{R}_{0}}\] \[\Rightarrow {{R}_{0}}=9.9\text{ }k\Omega \]
