Electroscopes
A qualitative measure of the charge on an object.

Van de Graaff Generator
Produces over 200,000 V and can be used for a variety of electrostatic experiments.

Electrostatic Pendulum – Charging by Induction
Conducting sphere bounces back and forth due to charging via induction.

Electric Field Inside and Outside of a Sphere
Uses the Van de Graaf, a hollow sphere, and an electroscope to show that charge accumulates on the outer surface of the sphere, but not inside.

Electric Field Inside and Outside of a Cylinder
Shows that any excess charge is located entirely on the outer surface of a conductor.

Electric Field Apparatus
Displays electric field lines between two probes, plates, or concentric circles.

Parallel Plate Capacitor
A large parallel plate capacitor with variable distance between the plates.
