A) \[0.1V, 1\mu A\]
B) 0.1\[0.15V, 10\mu A\]
C) \[0.015V, 1A\]
D) \[0.0075V, 5\mu A\]
Correct Answer: D
Solution :
\[{{\operatorname{R}}_{o}}=2k\Omega ,\,\,{{\operatorname{V}}_{o}}=2V,\,\,{{R}_{1}}=1.5k\Omega ,\,\,\,\beta =200\] \[{{A}_{v}}=\frac{{{V}_{o}}}{{{V}_{1}}}=\beta \frac{{{R}_{o}}}{{{R}_{1}}}\] \[\frac{2}{{{V}_{1}}}=\frac{200\times 2k\Omega }{1.5\operatorname{k}\Omega }\] \[{{V}_{1}}=0.0075\] \[{{\operatorname{V}}_{1}}={{I}_{b}}{{R}_{1}}\] \[{{I}_{b}}=5\mu \operatorname{A}\]
