Oh, yes we are only dealing with ideal op amps. But how do I know that the output is low?

Ok, but I've only solved before with negative feedback. How do I do it with positive feedback?

Well that's the diagram she gave us... So I'm not sure. I don't really understand that much about op-amps in particular. She just introduced the concept, but the homework is due today!

Homework Statement I'm looking at a larger circuit, but part of the problem is clearly an application of a voltage divider. The input voltage goes through a resistor (let's call it R1, it's value is 3kohms) and then it hits a node at which point it can go through R2 or R3 (12 and 6kohms...

Homework Statement Given the attached figure (with values as shown on the op-amp) find Vo and io. Homework Equations None 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...
