    In a common emitter amplifier, using output resistance of 5000 ohm and input resistance of 2000 ohm, if the input signal voltage is 10 mV and\[P\text{ }=\text{ }50\], calculate output voltage & power gain

    A) 1.25V, 6250      

    B)        3V, 6250

    C) 1.5V, 3050       

    D)        None of these

    Correct Answer: B

    Solution :

    Voltage gain = \[\beta \,\,\frac{{{R}_{out}}}{{{R}_{in}}}\] Power gain = \[{{\beta }^{2}}\,\,\frac{{{R}_{out}}}{{{R}_{in}}}\]
