Van de Graaff Generator - Motor driven, large

Product Code: 1217900

Useful for electrostatics experiments, where continuous source of high voltage is needed. A motor driven assembly encased in a sturdy metal box. The motor driven lower roller rotates the upper roller assembly located on top of the insulated Perspex pipe through a removable flat rubber belt. The continuous rotation of rubber belt results in accumulation of charge on the one piece near spherical metallic dome, charge being transferred continuously from rubber belt through charge collecting combs. Comprises a two piece bigger, spherical dome of diameter about 275mm, fixed on top of a bigger Perspex pipe, with complete assembly mounted on a sturdy sheet metal casing. Additionally, the base also incorporates an electronic variable speed control for driving the heavy duty motor of the generator. The bigger sized dome increases the charge capacity of the apparatus resulting in higher build up of electric potential, this process accelerated by bigger heavy duty motor and other design changes incorporated in the instrument. Provides for necessary adjustment in all the critical components. Comes with a discharger mounted on a long insulated handle, one side of the discharger being hemispherical, while other pointed to allow an effective demonstration of lighting conductor.
