The Van de Graaff generator uses this trick and two others to generate the high voltage needed to make a spark. The first trick When the balloon made contact with your hair, the molecules of the rubber touched the molecules of the hair. When they touched, the molecules of the rubber attract electrons from the molecules of the hair.. A Van de Graaff generator is a device used for building up extremely high potential differences in the order of a few million (as high as 20 million volts). Currently, Van de Graaff generator produces a potential difference of 5 Mega volts. The Van de Graaff generator was designed by Robert Jemison Van de Graaff in1929 A.D
A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate electric charge on a hollow metal globe on the top of an insulated column, creating very high electric potentials.It produces very high voltage direct current (DC) electricity at low current levels. It was invented by American physicist Robert J. Van de Graaff in 1929 ALSO: VandeGraaff Tricks and Demos, and see the VDG FAQ Page. Above is the basic explanation of the VDG operation. Real Van de Graaff generators have added complexity, and commercial units will often have differing details. REVERSED POLARITY Van De Graaff generators: high voltages, but safe. Although the voltages involved in Van De Graaff generator sphere charges and sparks are high - upwards of 400,000 volts for larger commercially-available models - they are generally very safe to use, even with young children. These machines have been in use in classrooms, universities, museums. The Van de Graaff generator subsequently became the basis for a modern kind of linear accelerator called the pelletron. The difference between them was the method of transfer of charged particles. If the generator they were transmitted using a dielectric tape, then the pelletron - a metal chain
