A) \[80\]
B) \[4.2\]
C) \[3.8\]
D) \[76\]
Correct Answer: C
Solution :
We have, \[a=\frac{{{i}_{c}}}{{{i}_{e}}}=\frac{{{i}_{c}}}{{{i}_{c}}+{{i}_{b}}}=\frac{19{{i}_{b}}}{19{{i}_{b}}+{{i}_{b}}}=\frac{19}{20}\] Voltage gain \[=\frac{19}{20}\times \frac{4}{1}=3.8\]You need to login to perform this action.
