A) \[5\times {{10}^{4}},5\times {{10}^{5}}\]
B) \[5\times {{10}^{4}},5\times {{10}^{6}}\]
C) \[5\times {{10}^{4}},2.5\times {{10}^{6}}\]
D) \[2.5\times {{10}^{4}},2.5\times {{10}^{6}}\]
Correct Answer: C
Solution :
\[{{V}_{gain}}=\left( \frac{\Delta {{I}_{C}}}{\Delta {{I}_{B}}} \right)\frac{{{R}_{out}}}{{{R}_{in}}}\] \[=\left( \frac{5\times {{10}^{-3}}}{100\times {{10}^{-6}}} \right)\times {{10}^{3}}\] \[=\frac{1}{20}\times {{10}^{6}}=5\times {{10}^{4}}\] \[{{P}_{gain}}=\left( \frac{\Delta {{I}_{C}}}{\Delta {{I}_{b}}} \right)({{V}_{gain}})\] \[=\left( \frac{5\times {{10}^{-3}}}{100\times {{10}^{-6}}} \right)(5\times {{10}^{4}})\] \[=2.5\times {{10}^{6}}\]You need to login to perform this action.
