Van De Graaff Generator, Motor Driven, Small

Useful for electrostatics experiments, where continuous source of high electric potential is needed. A motor driven assembly encased in a sturdy metal box made of Aluminum extrusion with insulated plastic side supports for safety. The motor driven lower roller rotates the rubber belt through an other roller at the top. The charge collecting combs present near the top roller continuously transfer the charge to the spherical metallic dome having smooth and polished surface free of any surface imperfections and without any sharp corner or edge to minimize charge leakage. On bringing earth edd is charge sphere, sufficiently close to the charged dome,transfer of charge takes place in the form of electric spark jumping from dome to the discharge sphere. Under favorable conditions, it can develop electric potential up to 200kV, with a spark of up to 70mm length. 4mm socket terminal provided at the bottom for earthing and another 4mm insert on top of the dome for charge transfer or for mounting accessories. Provides for necessary adjustment in all the critical components.
Supplied complete with discharge sphere, mounted on a long insulated handle. Operates on 220-240V AC, 50/60Hz.
