Variable Capacitor

Plate capacitor used to investigate the relationship between charge, voltage and capacitance, as well as determining the dielectric constants. It is a high accuracy capacitor for electrostatic experiments. The fixed and mobile plate is highly insulated. The solid aluminum plate capacitor around 150mm diameter and 3mm thick. The capacitance is adjustable from 2.3 to 280pF. It consists of a fixed and a movable plate on a guide rail. A centimeter scale is used to read the plate spacing. The device is supplied with three dielectric sample plates made of acrylic, PVC and cardboard. Supplied without LCR meter.

A device for demonstrating conductive & inductive electricity. It consists of two parallel plates mounted on insulated pillars so that the space between the plates can be adjusted and the glass or acrylic dielectric (insulated plates between them) can be removed or placed between the plates. Also included a pair of pith balls suspended by threads from pillars. Operatable on Wimshurst Machine.
Base: Wooden, 300mm x 175 mm (approx.)
Plates: Round, diameter 125mm (approx.)
Height: 250mm (approx.)

Mounted in a metal base with 4 mm sockets.

The electrolyte capacitor large (10000µf, 25V) mounted on a base, suitable for demonstrating stored energy.
Overall dimension: 105x75x115 mm approx.(L x W x H )

It has two 4mm safety sockets and 1 bulb 12V/21W, horizontal filament.

An apparatus for determining the temperature coefficient of resistance. It consists of a coil of insulated iron wire wound non-inductively on an insulating former and connected to terminals. The coil is enclosed in a glass test tube with a stopper. Thermometer not included in the scope of supply.
Tube size : 150x 25 mm approx.
Dimensions: 200x 50 mm approx. (Overall)
