Paul and Eric,
Given three light bulbs in series. Hook em up to a battery. Which bulb
lights first/last?? C'mon now, can't all be the same time. Doesn't the
electrical "message" travel at the speed of light so that in fact the
bulb furthest from the terminals will light last?
Thankfully, my students won't let this rest....
