Van De Graaff Generator

The Generator consists of a dome supported by a pillar and rubber belt driven by an electric motor concealed in the metal base. Static electrical charge is produced by friction between this band and two rollers. The charge is removed from the belt by a metal gauze and stored in the dome. The motor is powered using mains supply (230 V). The base is fitted with a 4 mm diameter socket which can be used either for supporting a conducting sphere (fitted with cranked rod support) or for wire connection to a separate conducting sphere. A cover is supplied to keep the Van de Graaff free from dust when not in use. This model will generate 200,000 - 400,000 volts depending on humidity levels. The kit includes demonstrations that cover all aspects of electrostatics such as charge conservation and transfer, conductors, insulators, ionisation. The grounded base mount discharge wand can be removed. The typical discharge arch is 2 8 cm. The set includes: Van De Graaff Discharge wand Dust cover Faraday's pail Perspex cylinder Head of hair Point discharger Neon bulb Electric whirl Pillar with suspended metal sphere Comb An activity guide that explains how to use all attachments. Size: dome diameter: 22 cm, discharge wand diameter: 10 cm; overall size: 61 cm high with 23 cm x 25 cm base.
