Description

The Generator consists of a
conducting sphere(the dome)
supported by a plexiglass pillar
and a rubberbelt driven by an
electric motor concealed in the
metalbase. Static electrical charge
is produced by friction between
this band and two rollers, one of
polythene, theother of plexiglass.
The charge is removed from the
belt by a metal gauze and stored
in the dome. The electricmotor is
driven from the mains supply, using
a three-wirecable. 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 plexi
glass rod). A dust cover is provided to keep the Vande Graaff free
from dust when not in use.
