How fast is an electron in a wire and how fast is electricity? An electron moves surprisingly slow, slower than a snail, while electricity moves at near the speed of light. Electrons move at what's called the drift velocity. This video illustrates all this in an entertaining and informative way. Enjoy!
ERROR!!! At 2:00, I say 0.0007 m/s. That should have been 0.00007 m/s.
