Two circular plates of 100 mm diam are carried on a pair of insulated pillars. The gap is adjustable. A support for interposing sheet of dielectric material is provided, on an insulated base. The terminals are provided with 4 mm sockets for connection and additional vertical sockets to carry a pair of suspended cork balls (supplied with the apparatus).

Two rigid PVC plates,each with a terminal and metal foil sheets attached, on support mounted on a slider. The supports are designed so that the plates may be set either at right angles or parallel to the slideways to show the effects of varying the separation or varying the effective area respectively. The slideway consists of a double horizontal rod bent at one end to fit a cast base & shaped at the other to form a stable foot.

A spherical conductor on insulating stand with two hollow hemi-spheres, each with insulated handle, to show that electrostatic charge resides on outer surface.

but with a pivoted aluminium pointer moving over the scale. eliminates problem of breaking of leaves and their refixing.
 

Net with cord, on insulated pillar on a metal tripod base, to show electric charge resides on outer surface of a conductor
