    What is the voltage gain in a common emitter amplifier when input resistance is 3, and the load resistance 240 with p = 60:

    A)  8.4                                        

    B)  4.8

    C)  2.4                                        

    D)  480

    Correct Answer: D

    Solution :

                     Voltage gain = current gain \[\times \]resistance \[=\beta \times \frac{{{R}_{v}}}{{{R}_{i}}}\] \[=60\times \frac{24}{3}=480\]
