Physics Instruments

Comprising of Faraday Pail, Bouncing Ball, Head of Hair, Charge Attractor and Icons in Motion Simulator.

The two plates are supported in two rigid uprights and driven by belt in opposite direction. They are heavy, high resistance plastic with sectors of aluminium sheet. Two leyden jars (condensers) made from corning glass and aluminum foil. The whole machine is mounted on a wooden base.

Produces high voltage electricity for the use in electrostatic experiments. Dimensions height 780mm Sphere 250mm 220/240V A Spare belt

Hand operated on base. A metal sphere surrounds the upper pulley assembly and charge accumulates on the sphere, which is insulated by a plastic column supporting the pulley assembly. The charge builds up until electrical breakdown of air surrounding the sphere occurs. Supplied with a discharging sphere.

Mounted on a base plate 230x90mm approx, which carries a hand drive pulley 120mm dia. coupled to the smaller dynamo pulley by a rubber belt to give a step-up ratio. Electrical output is via a pair of 4mm sockets and a light emitting diode is provided as a simple output indicator. The model may also be used as a motor on a 6-8V D.C. supply.

A 250W tungston filament bulb available with either Bayonet or screw fitting, internally silvered.
A Bayonet Fitting
B Screw Fitting

S.B.C. double contact brass, lamp holder mounted on rectangular moulded base, with two 4mm socket connections. Lamp Holder As above but M.E.S. lamp holder

With detachable snap on plastic cover, metal thread terminals, silver contacts. Dome gong dia. 75mm. For use on 3 to 4.5V A.C./D.C. supplies.

Tinplate box with 130mm sides. The vertical faces of the box are blackened, roughened, varnished and polished respectively. The top opening is 75mm dia. and is fitted with a lid. The apparatus is filled with water maintained at boiling point by a low bunsen flame. Infa red sensors may be used to compare the relative radiant heat output from each of the four faces.

All the components of an electric bell are mounted on a large panel. All wiring is visible and parts are of large size. Operates on 3-4 volts D.C.

Low voltage single pole double throw, molded base with plated spring metal contacts and screw connectors.

Low voltage, double pole double throw, may be used as a changeover switch with appropriate connections, moulded base with plated spring metal contacts and screw connectors.

It contains the solar panel, motor fan and other components to demonstrate the use of solar energy. Complete in a box with leaflet explaining solar energy.

A small motor, which operates from 1.5-4.5volts D.C. with small pulley.
