question_answer
A transistor connected at common-emitter mode contains load resistance of\[5\,k\,\Omega ,\]and an input resistance of\[1\,k\,\Omega \]. If the input peak voltage is 5 mV and the current gain is 50, find the voltage gain:
A) 250
B) 500
C) 125
D) 50
E) 75
Correct Answer:
A
Solution :
Voltage gain\[=\frac{{{R}_{out}}}{{{R}_{in}}}\times \beta \] \[=\frac{5}{1}\times 50\] \[=250\]
