Do you have a link to an explanation of what current is which makes the movement of charged particles almost irrelevant? If it turns out I (and Wikipedia, and all material I've seen on the topic) is wrong, I'd certainly love to know. I'm just interested in this stuff; I have only taken introductory courses at university and learned on a hobby basis, I haven't taken advanced courses.
- megous 4y agoI said it's irrelevant to transfer of power. (I guess I kinda overstepped with it being irrelevant to electrical current, yes :)) And power is what destroys things, mostly, by over heating them and transforming them into a different shape that no longer functions as expected. > Do you have a link to an explanation of what current is which makes the movement of charged particles almost irrelevant? Not really, but consider when was this slow drift (~3 mm/s) of electrons ever of interest/topic in your education, instead of much faster changes in charge distribution on the surfaces of conductors caused by (or creating) electrical fields? 3 mm/s is extremely slow, you'd very much notice if any phenomenon you routinely worked with in EE courses was this slow.
