1. The problem statement, all variables and given/known data Determine the Op amp gain of the following circuit. V1 = 1v Vo = 4 V 2. Relevant equations A = Vo/ VI 3. The attempt at a solution Using voltage division I determined the voltage for the node at the +ve terminal VI = V1(1k/ ([1000 + 1]k)) = 1/1001 V Vo = 4v Given Therefore A = Vo/VI = 4/(1/1001) = 4(1001) However the answer is A = 4/(4/1001) = 1001 So somehow I'm off by a factor of 4. I am really unsure why VI is 4/1001. Thank you so much for your time.
