Answer» AVan de Graaff generatoris anelectrostatic generatorwhich uses a moving belt to accumulateelectric chargeon a hollow metal globe on the top of an insulated column, creating very highelectric potentials. It produces veryhigh voltagedirect current(DC) electricity at low current levels. It was invented by American physicistRobert J. Van de Graaffin 1929.Thepotential differenceachieved by modern Van de Graaff generators can be as much as 5 megavolts. A tabletop version can produce on the order of 100,000 volts and can store enough energy to produce a visible spark. Small Van de Graaff machines are produced for entertainment, and for physics education to teachelectrostatics; larger ones are displayed in somescience museums. |
