Van de Graaff Generator, Small Electric
Product Code : EL-PLE-13154
Eduscope India is a leading Van de Graaff Generator, Small Electric
Quick Answer: Van de Graaff Generator, Small Electric is a compact, single motor-driven electrostatic generator that builds up a 100,000 volt potential on an aluminum sphere to demonstrate high-voltage static electricity.
A Van de Graaff generator works by using a continuously moving belt to mechanically carry electric charge from its base up to a hollow metal sphere; because charge on a conductor resides on the outer surface, the charge deposited there keeps accumulating and builds up a very high electric potential. The operating principle was devised by Robert J. Van de Graaff in 1929, and this model is EduScope India's smaller, single (motor) drive version, part of the physics demonstration kit India range under Physics Lab Equipment. Its charge generation system is built around a neoprene belt mounted on insulating rollers, with metal charge transfer combs that deposit and strip charge from the belt as it travels, housed in a clear tube so students can watch the belt and rollers directly while the generator runs; the charge collected in this way builds up on an aluminum collector sphere, and the whole assembly sits on an electric motor drive mounted on a sturdy base. In the classroom, it demonstrates the visible effects of high-voltage static electricity safely, since the current delivered at the sphere stays very low even though the potential is high, making it a longstanding staple for showing charge accumulation and static repulsion.

EduScope India's physics equipment, including this Van de Graaff Generator, is exported to Horn of Africa markets such as Ethiopia, Sudan, Djibouti and Somalia, supporting school and institutional science lab equipping in the region.
As part of its physics demonstration kit India catalogue, EduScope India regularly supplies this generator through bulk institutional and government lab-equipment orders, school chains and CSR-funded science-education programs.
It is part of EduScope India's Physics Lab Equipment range. Laboratories that need a larger or more versatile electrostatic generator may prefer the Van de Graaff Generator, Dual Drive, offering both hand-cranked and motor-driven operation. The Wimshurst Generator builds high voltage through induction rather than a moving belt, giving a useful comparison in electrostatics teaching, while the Light Leaper Accessory is designed for use with generators of this kind, adding a visible multi-spark demonstration.
