A) \[0.33k\Omega ,1.5\]
B) \[0.67k\Omega ,200\]
C) \[0.33k\Omega ,300\]
D) \[0.67k\Omega ,300\]
Correct Answer: D
Solution :
input current \[=15\times {{10}^{6}}\] output current \[=3\times {{10}^{3}}\] resistance output = 1000 \[{{V}_{input}}=10\times {{10}^{3}}\] Now \[{{V}_{input}}={{r}_{input}}\times {{i}_{input}}\] \[10\times {{10}^{-3}}={{r}_{input}}\times 15\times {{10}^{-6}}\] \[{{r}_{input}}=\frac{2000}{3}=0.67K\Omega .\] voltage gain =\[=\frac{{{V}_{output}}}{{{V}_{input}}}=\frac{1000\times 3\times {{10}^{-3}}}{10\times {{10}^{-3}}}=300\] Option [d]You need to login to perform this action.
