yeah, electrical power propagates way faster than electrons drift (and the power flux is primarily outside the wire, but that's a fun story for a different day)

One way to think about it is as a newton's cradle sorta deal. It's not perfect, but fairly close. Also maybe flicking a jump rope - energy propagates, but the bits of rope don't move from beginning to end.
- dillonmckay 7y agoBefore I read your comment, I thought the description sounded like Newton’s Cradle. Flicking a jump rope sounds more akin to AC to me, though. Maybe, pulsed DC? What about a train or bumper car analogy (not joking)? I would really like to see this as a visualization.
