A) 1900 and ,1800
B) 1900 and 1805
C) 5525 and 3591.
D) 1805 and 1900
Correct Answer: B
Solution :
Given, \[\alpha =0.95,\,{{R}_{0}}=400\times {{10}^{3}}\,\Omega \] \[{{R}_{i}}=200\,\Omega \] As, voltage gain\[=\alpha \frac{{{R}_{0}}}{{{R}_{i}}}\] \[=0.95\times \frac{400\times {{10}^{3}}}{200}\] \[=1900\] Power gain = Voltage gain \[\times \]Current gain \[=1900\times 0.95\] \[=1805\]
