Hey, guys.. So im taking some electrical engineer classes and i could really use your help on one of the questions im stuck on.(adsbygoogle = window.adsbygoogle || []).push({});

So my proff talked about opamps and said we would not be using positive feedback and skipped it. Question number two has both positive and negative feed back. I have no idea how to do this question?

#3, because there is an open circuit can i say there is no current flowing in the top and bottom wire and therefore the Thevenin Voltage is just 24V? I know to find the current i have to put a shunt between a and b but any more tips?

Im struggling overall with the rest of the questions so any help would be appreciated!

Thanks guys! XOXO
