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, power cord, electrostatics accessories kit and an experiment guide with activity questions for learners.
