Mechanical Model of Resistance


A board of nails, a hose, and a box of ping pong balls

Concept Overview:

1. Visualization of resistance using nails and ping pong balls.

Lecturer Procedure

Step(s) to Follow Expected Result

1. Place 2 balls at the top of the board, one on each side.

2. Release balls at the same time.

The ball will move more quickly through the side with less nails, thus representing how charges flow through a material with less resistance.
