    The correct curve between voltage gain \[({{A}_{v}})\] and load resistance \[({{R}_{L}})\] is

    A)                             

    B)                     

    C)                             

    D)                     

    Correct Answer: C

    Solution :

                       According to \[|{{A}_{v}}|\,=\frac{\mu }{1+\frac{{{r}_{p}}}{{{R}_{L}}}}\] as RL increases Av also increases. When RL becomes too high then Av = maximum = m Hence only option (c) is correct.
