Maybe that's why I never understood electricity if the mental model they teach is just physically wrong...

The OP is an example when they talk about cold penentrating which makes no sense.

I should have made it more clear that I was trying to recreate the mental model that my teacher’s explanation gave me, at the time. I realized after posting it that my model was wrong—I know it’s really the other way around.

All models are wrong, but some are useful.
