That is a good point, but, it would still be really nice if the convention for current just so happened to match the flow of electrons through a wire since it is the common case. At least, I remember that being pretty disorienting for me at times in some electrical engineering classes. Wish I could remember something specific though!
Do appreciate you pointing out some counter examples though, always fun.
- shadowgovt 2y agoIt definitely matters when you start actually caring about electrons leaping through space over long distances. Like... You'll get the wrong answer if you think the electrons in a CRT go from the screen to the gun, or if it's positively-charged particles that are causing carbon deposition inside a vacuum tube. But that actually turns out to be (for most people) a specialized context. I'm startled to discover (because I was in the same camp as you) that the math is so symmetrical that it really almost never matters how the physical charge-carriers are moving, since it's the change in electric field that is causing things to happen.
