Hand Crank Van De Graaff Generator, 7.9" Sphere
The van de Graaff generator is a simple device designed to create large voltages with low current. It can be used to dynamically 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 hand crank operated Van De Graaff Generator measures 22" tall and produces up to 100,000 Volts and is 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 Sphere, assembled base, 4mm grounding wire, and an experiment guide with activity questions for learners.
