    What is the voltage gain in a common-emitter amplifier where input resistance is 3 0 and load resistance is \[24\,\Omega \]? \[(\beta =0.6)\]

    A)  2.2            

    B)  1.2

    C)  4.8            

    D)  8.16

    Correct Answer: C

    Solution :

    Voltage gain = current gain x resistance gain Resistance gain \[=\frac{load\text{ }resistance}{input\text{ }resistance}\] \[=\frac{24}{3}=8\] Current gain = 0.6 Hence, voltage gain \[=0.6\times 8=4.8\]
