A visual physical model for Ohm's Law uses a wood board with nails in it and metal balls. The nails in a board represent a fixed amount of electric resistance in a wire.
 
  As the metal balls roll through the nail obstacle course, they run into nails and bounce in various directions. The balls represent the charge carriers in a current; the greater the speed of the balls running through the nails, the greater the current represented. The electric potential energy difference between the ends of the wire is represented by the tilt of the board, because a greater tilt represents a greater difference in gravitational potential energy. Explain how this analogy works.
