Description: This is a visual model of resistance on a microscopic scale.
When the lead ball hits a nail, this represents resistance to the flow of the “electron”.
Equipment:
- Resistance board
- Lead shot
- Box to catch the lead shot
- Jack stand and C clamp
Setup Procedure:
- Attach the jack stand to the table with a C clamp.
- Rest the resistance board on the jack stand and place the box under the bottom of it.
Demonstration Procedure:
- Roll the lead beads down the board and watch how they hit the nails. You may either drop one or multiple balls. The more balls illustrates more current though the effect is the same.
