Here' a beginner OpAmp question.
First of all. YES I KNOW the V- connection of the OpAmp really should be connected to -5V and not ground but THAT'S the point of this question.
The inverting amp does as I'd expect and the blue trace stays at zero when the input (green trace) is positive.
The non-inverting amp, on the other hand, is fine up until the input goes beyond about -0.7V then you get those huge spikes where I'd expect it to stay at zero.
What's happening here when the opamp is powered incorrectly this way?
