How a Van de Graaff Generator Works

Detailed explanation down to the electrons and protons on how a Van de Graaff generator works. Includes the triboelectric effect between the rollers and belt, corona discharge and photoelectric effect between the belt and brushes/combs, and Faraday ice pail effect at the top dome/bowl. Shows how arcing/sparks happen and how strong electric fields contribute to creating ions and plasma for making air gaps electrically conductive. This video has correct English captions.
