Comprising two metal discs, with variable separation, supported on insulating pillars & provided with insulating handles on the ends of the adjustment slide rods, 4 mm sockets too are drilled onto the ends of the rods. A rectangular glass plate is supplied which mounts in clips between the two discs & may be easily replaced by a plate of so..

Biots Apparatus for Physics Lab is a spherical conductor on insulating stand with insulated handle, to show that electrostatic charge resides on outer surface...

Cellulose Strip For producing positive charges relative to polythene when rubbed by woollen rubber. Overall Dimensions : 250 x 25 x 1.5 mm...

Coulomb's law states that the force of attraction or repulsion between two charged bodies is proportional to the magnitude of the charges and inversely proportional to the square of the distance between them. This device will allow students to not only observe this phenomenon, but quantitatively measure it. Apparatus includes a rugged woode..

The apparatus includes a clear Petri dish 90mm dia. x 12mm depth. The transparent base (140 x 125mm) allows the pattern to be projected via an overhead projector system. Alongside each terminal is a thumbscrew system which permits fine adjustment of the electrodes. Six electrodes are supplied, 2 'point source', 2 'line source' and 2 circular rings ..

The item can show the dispersive power of the points thanks to the mechanical effect...

Measures electric charge or electrical potential difference. Show how two similarly charged objects repel! Pith-balsa wood ball type...

Electrostatic kit is a set of tools which can be used to do experiment concerning the electrostatic. Electrostatic is produced by rubbing acetate cellulose or polietilen strip with existing wool. Completed with equipment that can be used for experiments : electrostatic force,capacitance, the law of conservation of charge.Consists of:1 pc Electrosco..

A metal case with 4 mm earthing socket with glass window. A metal disc passes through an insulating polythene bush and ends in a flat support for “gold leaf” with a transparent scale to show quantum of deflection...

A hand driven Van de Graaff generator, which is a very effective unit for introducing electrostatics. The length of the sparks generated is wholly dependent upon the speed at which the user turns the handle but sparks of around 20-30mm are comfortably achievable..

An efficient design for all the usual electrostatic experiments and for where a continuous source of high voltage is required. It has a strong metal base with profiled hand grips, housing a quiet running a.c. motor. The discharge sphere may be plugged into the base or supported separately, linked to the arching post with a standard 4mm connecting l..
