Lightning rod
Demonstration model of a lightning rod: corona discharge from the tip and the principle of lightning protection in four experiments on electrostatics.
The model is assembled on a base with connection terminals and includes a sharp metal lightning rod, a metal ball and an aluminum plate. The apparatus allows for four demonstrations: corona discharge from the tip and facilitated flow of charge from conductors of small radius of curvature, the dependence of the spark discharge on the shape of the electrode when comparing the tip and the ball, the operating principle of a lightning rod with an explanation of the formation of lightning, the influence of the height of the lightning rod on its protective properties. The device is used in demonstrations on electrostatics in physics lessons.
- 1.Base with connection terminals - 1 pc.
