LEEI-14 Van De Graaff Generator


  • Ideal apparatus for demo

  • Low price

  • Accessories included


A Van De Graaff generator is an electrostatic high-voltage generator which uses a moving belt to accumulate high amounts of electric potential on a hollow metal globe. It provides a high-voltage electrostatic source for the demonstration of charge nature, lines of electric force, spark discharge, parallel plate capacity, and electrostatic precipitation.
