School Lab Van De Graaff Generator With Accessory Kit

School Lab Van De Graaff Generator With Accessory Kit

The electric motor is driven from the mains supply, using a three-wire cable.  
The base is fitted with a 4mm diameter socket which can be used either for supporting a conducting sphere (fitted with a cranked rod support) or for a wire connection to a separate conducting sphere (fitted on a plexiglass rod).  
The Generator consists of a conducting sphere supported by a plexiglass pillar and a 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, one of polythene, the other of plexiglass.  
The charge is removed from the belt by a metal gauze and stored in the dome.  
A dust cover is provided to keep the Van de Graaff free from dust when not in use.
