Revision as of 15:34, 30 August 2005 by Reddi (talk | contribs)(diff) ← Previous revision | Latest revision (diff) | Newer revision → (diff)An electrostatic generator is a mechanical device which produces a high voltage electrical output at very low current. Electrostatic generators are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. Electrostatic generators such as the Pelletron and the tandem generator also find use in physics research.

Machine examples
Examples of electrostatic generators include:
- Electrophorus is a single-plate capacitor used to produce imbalances of electric charge via the proces of electrostatic induction.
- Wimshurst machine is a form of electrical generator developed by British inventor James Wimshurst, who was born in 1832.
- Van de Graaff generator is a machine which uses a moving belt to accumulate very high charges on a hollow metal globe. The potential differences achieved in modern Van de Graaff generators can be up to 5 megavolts.
- The Testatika resembles a Wimshurst machine. It was built by German engineer, Paul Suisse Bauman, and promoted by a Swiss community, the Methernithans.
