I have a pretty solid grasp of electronic theory but for some reason op amps are confusing the ever living *frick* out of me.
Edit:. Thanks to those of you trying to dumb it down for me! I have an electronics tech assessment with Garmin on Thursday, and though I’ve worked on electronics for 14 years, including 9 in the military, those 9 years were in the Marines. I understand things better when they’re sketched with crayons 🙂

As used in a typical (negative feedback, amplifying) configuration: Imagine you are driving an incredibly powerful car. And when you step on the gas, the car throws you back so hard your foot withdraws from the gas pedal. And when it decelerates, your foot goes back on the gas. Now, by careful adjustment of the seat and seat belt, like careful selection of the components surrounding the op-amp in the circuit, you obtain a stable situation where your tiny pressure on the pedal translates to a tremendous pressure from the engine on the car.
