The Van De Graaff generator is a simple device designed for electrostatic experiments and where continuous source of high voltage is required. It can be used to demonstrate several physical concepts, including: electrostatics, conservation of charge, conduction, and ionization. Static electricity is a familiar concept we encounter on a daily basis. It explains why static cling affects our clothes, the shock we sometimes experience when touching a doorknob on a dry winter day, and why we can cause a friend's hair to stand on end by “charging up” a balloon.
This DC motor driven Van De Graaff Generator measures 22" tall and produces up to 220,000 Volts. Ideal for demonstrating the transformation of energy from mechanical to electrical. Set includes a polished and hand spun 7.9" Van de Graaff Dome, 4" discharge wand, assembled base with attached DC motor, 3 prong power cord, electrostatics accessories kit and an experiment guide with activity questions for learners.
