    In triode amplification voltage gain depends on:

    A) \[\mu ,RL\]and input voltage

    B)        \[{{R}_{P,}}{{R}_{L}}\]and \[\mu \]         

    C)        \[\mu {{R}_{P,}}\] and input voltage

    D)        \[{{R}_{P,}}\mu \]and\[{{g}_{m}}\]

    Correct Answer: B

    Solution :

    Voltage gain in triode amplifier \[A=\frac{\mu {{R}_{L}}}{{{R}_{P}}+{{R}_{L}}}\] \[\therefore \] A depends upon \[\mu \], \[{{R}_{P}}\] and \[{{R}_{L}}\].
