# Two amplifiers ar

Let A1 = 10 (Voltage gain of the first amplifier)

and A2 = 20 (Voltage gain of the second amplifier)

Vi = 0.01 V (Input signal voltage)

Let, Output AC signal voltage = Vo

We have the relation:

V0 = A × Vi

Output after the first stage VO1 = A1 × Vi

Then, output after the 2nd stage VO2 = VO1 × A2 = Vi × A1 × A2

Hence, the final output = VO = 20 × 10 × 0.01 = 2 Volts

Therefore, the output AC signal of the given amplifier is 2 V.
