    What is the voltage gain in a common emitter amplifier, when input resistance is \[3\,\Omega \] and load resistance is \[24\,\Omega \] with \[\beta =60\,?\]

    A)  480                                       

    B)  2.4  

    C)  4.8                        

    D)         8.4

    Correct Answer: A

    Solution :

    \[{{A}_{v}}=\beta \times \frac{{{R}_{2}}}{{{R}_{1}}}=60\times \frac{24}{3}=480\]
