    For a common base amplifier, the values of resistance gain and voltage gain are 3000 and 2800 respectively. The current gain will be

    A)  \[1.1\]

    B)  \[0.98\] 

    C)  \[0.93\]

    D)  \[0.83\]

    Correct Answer: C

    Solution :

    [c] Current gain, \[\alpha =\frac{{{A}_{V}}}{{{A}_{R}}}=\frac{2800}{3000}=0.93\]
