A) 9900
B) 99
C) 9.9
D) 990
Correct Answer: D
Solution :
Voltage gain =\[=\beta \times \] resistance gain \[\beta =\frac{\alpha }{1-\alpha }=\frac{0.99}{(1-0.99)}=99\] Resistance gain \[=\frac{10\times {{10}^{3}}}{{{10}^{3}}}=10\] Voltage gain\[=99\times 10=990\]You need to login to perform this action.
