I've read quite a few guides on op amps, and most are very similar. I still don't quite get them, though.
Rule: The output always acts to make the input voltages the same.
But there are inverting and non-inverting inputs. Which does the op amp act on? For example, if it's open loop, and the inverting input is lower than the non, does the ouput go high to raise the inverting, or low to lower the non?
