Voltage gain of the first amplifier, V1=10, Voltage gain of the second amplifier, V2=20, Input signal voltage, V1 = 0.01 V, Output AC signal voltage = V0 The total voltage gain of a two-stage cascaded amplifier is given by the product of voltage gains of both the stages, i.e., V=V1×V2=10×20=200 V=
V0
V1
We have the relation: V0=V×V1=200×0.01=2V, Therefore,the output AC signal of the given amplifier is 2 V.
