Hand-Driven Van de Graaff Generator and Accessories, For Demonstrating Electrostatic Principles, Each

Details

The Van de Graaff generator is a simple device designed to create large voltages with low current, ideal for dynamically demonstrating several physical concepts, including electrostatics, conservation of charge, conduction, and ionization. Static electricity is a familiar concept we encounter daily, explaining 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 inches tall and produces up to 100,000 volts, making it ideal for demonstrating the transformation of energy from mechanical to electrical. The set includes a polished and hand-spun 7.9-inch Van de Graaff dome, a 4-inch discharge sphere, an assembled base, a 4mm grounding wire, and an experiment guide with activity questions for learners.
