1. The problem statement, all variables and given/known data Hello, I have attached the problem below. I am trying to find the value for v1 - v2 and iA. The given values are V, RA, and R for the other resistors. There are no numbers. 2. Relevant equations It is given that the op amp is ideal, therefore v- = v+, and i- = i+ = 0 for both op amps. 3. The attempt at a solution I attempted the solution by using node analysis. iA = V/(3R + RA) (assuming that none of the current flows into the output of the op amp). The v1 value at the output of the first op amp should be v- of the second op amp. This becomes v+, and we can write in v1 at the point below v2. Therefore, the current in that case is v2-v1/R. We equate these two values for the current and get that v1-v2= -V*R/(3R + RA). However, my professor stated that this solution is incorrect. How do I proceed?
