Ohm's law demo

  1. Aug 29, 2013 #1
    I remember seeing a demo of collisions inside a conductor. It was a long board with nails representing the atom positions (a square lattice arrangement) and you would put a hand full of marbles at the top. The marbles will slide down but since they keep hitting the nails the velocity will be constant.
    Does anyone have a link to a video showing this demo?
    Thanks!
