A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate very high electrostatically stable voltages on a hollow metal globe on the top of the stand. The potential differences achieved in modern Van de Graaff generators can reach 5 megavolts. The Van de Graaff generator can be thought of as a constant-current source connected in parallel with a capacitor and a very large electrical resistance.

Not to be confused with the 1970s english rock band Van Der Graaf Generator, A Van De Graaff Generator is a device that produces static electricity in a consistent current by rotating a belt of triboelectric material (A triboelectric material is a substance that produces electricity when rubbed against another triboelectric material, such as a rubber balloon and human hair) such as silk inside of a metal sphere to allow for the sphere to receive a charge. The beauty of this method of generating static electricity is that because the belt never ends, a Van De Graaff generator can supply a consistent amount of electricity for extended periods of time.

abstract	A Van de Graaff generator is an electrostatic generator which uses a moving belt to accumulate very high electrostatically stable voltages on a hollow metal globe on the top of the stand. The potential differences achieved in modern Van de Graaff generators can reach 5 megavolts. The Van de Graaff generator can be thought of as a constant-current source connected in parallel with a capacitor and a very large electrical resistance. Not to be confused with the 1970s english rock band Van Der Graaf Generator, A Van De Graaff Generator is a device that produces static electricity in a consistent current by rotating a belt of triboelectric material (A triboelectric material is a substance that produces electricity when rubbed against another triboelectric material, such as a rubber balloon and human hair) such as silk inside of a metal sphere to allow for the sphere to receive a charge. The beauty of this method of generating static electricity is that because the belt never ends, a Van De Graaff generator can supply a consistent amount of electricity for extended periods of time. These devices have a very wide range of uses depending on the voltage produced by the particular model. Low voltage Van De Graaff Generators are a favorite at science fairs as enducers of funky hairdos, and a staple in physics classrooms where students must study electricity. Higher voltage models can also be used in particle accelerators which can use electricital energy to speed up the movement of particles. But as far as physics students who do not have an imminent desire to become quantum physicists should be concerned, Van De Graaff Generators are a means to produce static electricity, and a very fun way to do some funky science experiments (Just make sure that the knob stays at a safe voltage.) The Van De Graaff generator is the future.
