Product Summary
This set includes a conductive sphere with a hole in it. Demonstrate that static charge resides outside the surface of a conductive sphere by sampling the inside surface with the ball end of the proof plane. Also included is an oblong shape for demonstrating the difference in charge densities on a large-radius surface vs. a small-radius surface. The whole surface is at the same potential, and students seem surprised to find that the charge density is greater on the smaller end.
Features
- High quality nickel-plated ABS plastic shapes
- Non-conductive polycarbonate rods and stable support base
- Thumbscrew terminal for attaching a ground cable or lead from a voltage source.
Applications
- Use a Proof Plane to sample charge on the conical shape
- Using a Proof Plane to Sample Charge inside the Hollow Sphere

College / Physics
Compare and contrast the results of three different methods of charging: (1) rubbing two objects together; (2) touching a charged object to a neutral one; and (3) grounding a neutral object while it is polarized (charging by induction)....
