Good call.
In a nutshell, my unit tests for current-only, no op-amp, work well. 203 watts is correct here
When I introduce the op-amp circuit, AC/AC adapter, and calcVI(), the numbers get frantic
I’m trying to figure out where to start debugging. Maybe a bad solder joint? Maybe bad code? Maybe a melted LM358.
Mainly, if anyone has any ideas off the bat, I’ll give those a try. Else, I’ll start checking the physical connections to make sure those seem good.
