What is the gain for the inverting amplifier of the figure? Remember the gain of an amplifier is the absolute value of the ratio of Vout to Vin--that is, abs(Vout/Vin). Give your response in Volts. Give your response as a single number without additional characters or punctuation marks. Show all the steps to get full credit

What is the gain for the inverting amplifier of the figure? Remember the gain of an amplifier is the absolute value of the ratio of Vout to Vin--that is, abs(Vout/Vin). Give your response in Volts. Give your response as a single number without additional characters or punctuation marks.

Explanation / Answer

since this is an inverting amplifier the gain A(vout/vin)=-Rf/R1 where Rf is the equivalent feedback resistant

therefore, A=-(Rf)eq/R1 (Rf)eq=r2||r3 i.e r2*r3/r2+r3=329050410/71239=4618.96 ohm

now, A=-Rf/R1=4618.96/586= -7.88219
