Abstract
We describe an apparatus that enables students to study the electric fields and the associated surface charges for several different electrode structures including parallel plates, cylindrical rods over plates, and nested cylinders. The study involves the relations among potential difference, electric field, surface charge density, and total charge. These relations are confirmed to within a few percent.
