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 \[=1900\times 0.95=1805\]You need to login to perform this action.
