Description

In the experiment P3.1.5.1, an electric charge is collected from a charged hollow metal sphere using a charge spoon, and measured using a coulomb meter. It becomes apparent that the charge density is greater, the smaller the bending radius of the surface is. This experiment also shows that no charge can be taken from the interior of the hollow body.
