1. The problem statement, all variables and given/known data Given the attached figure (with values as shown on the op-amp) find Vo and io. 2. Relevant equations None 3. The attempt at a solution I figure that we're looking at an inverting operational amplifier and I used a voltage divider to find the input voltage [(90/90+10)]*1V = .9V. But I'm stuck on the rest. I don't think it was very well explained by my professor, and since no two op-amps look alike I'm just wondering about how to solve this problem but also how to approach these problems in general? Any help would be greatly appreciated!!!
