Solution
The voltage gain of a CE amplifier is 50. A sinusoidal ac of amplitude l 0 mV is applied as a signal. The output of the amplifier will be Sinusoidal ac voltage of amplitude 500mV.
Explanation:
Voltage gain = `"A"_"v" = "output"/"input"`
50 = `"output"/10"mV"`
`therefore "output" = 500"mV"`
