Are they taught the “electron theory” or the “conventional theory?”
Most people don’t know the difference between the two.
With vacuum tubes, we had (and still have) to remind ourselves that the EE’s current inside the tube goes from the cold thingie to the hot thingie, not the other way around.
Electrons? You mean the thingies that go from positive to negative? Or is it the other way around? I can never remember for sure. Why is it that sometimes you hook up the neutral wire on 220 and other times you don’t? Is that important?
