Gain of the first amplifier, V1 = 10
Gain of the second amplifier, V2 = 25
The total voltage gain of a two-stage cascaded amplifier is given by the product of voltage gains of both stages, i.e.,
V = V1 × V2
= 250
Input signal voltage, Vi = 10 mV=0.01 V
Let the output of the second stage = Vo
⇒Vo=2.5 V
