A) \[49\times {{10}^{3}}\]
B) \[2.5\times {{10}^{2}}\]
C) \[1.5\times {{10}^{2}}\]
D) 4.9
E) \[3.5\times {{10}^{3}}\]
Correct Answer: A
Solution :
Given, \[\beta =\frac{\alpha }{1-\alpha }=\frac{0.98}{1-0.98}=49\] \[\therefore \]Voltage gain\[=\beta \frac{{{R}_{2}}}{{{R}_{1}}}=49\times 1000=49\times {{10}^{3}}\]
