1. The problem statement, all variables and given/known data I need to find the gain in this question. 2. Relevant equations 3. The attempt at a solution I know gain will be Vo/Vs. I did many calculations to end up with Vs being 0. Would this be logical? I know ideal op amps will have infinite voltage gain, so if you divide by 0 then it will go towards infinity? So I'm not sure if that would be correct for this question.
