Conductive Shapes
These Conductive Shapes (one hollow and one conical) can be used to store charge or investigate the charge distribution on one or two spherical conductors.
Description
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.
