Diagram showing the discharge of a Van de Graaff generator, a machine that produces a static electric charge. The generator consists of a high-voltage supply that sprays"" a charge onto a continuously moving belt of insulating material. The charge is carried by the belt to accumulate on the exterior of a metal dome. When the charge is large enough an electrical discharge occurs via a spark between the dome and the small negatively-charged sphere." | |
