Comprising a resistance wire swg 24 stretched along a meter scale subdivided in mms and marked every cm. is clamped to stout brass plates so as to avoid end errors. A plated brass strip with 4 mm socket terminal is fitted along the meter rule to provide a two gap system for normal Wheatstone bridge work. Complete with jockey.

This wind power generator can be used to demonstrate the generation of electricity by a wind-powered turbine. Wind produced by the hand-cranked fan subsequently turns a second fan connected to a generator. When the fan rotates, it produces electricity and lights up a small bulb and a voltmeter. Instructions included.

Multistrand copper wire, PVC insulated, to carry 2 A, in multiple of 10 meters.

This device provides an effective and very simple clamping system for testing the strength of the ductile wires such as copper, sewing threads, fishing lines and human hair etc. The material is clamped between the washers with the help of a wing nut clamp and the wire is routed through the holes provided in the clamps. The strength is checked by attaching one of the clamps to the clamp provided in the laboratory and loading the lower clamp with slotted weights. A maximum of 15 kg of weight can be hanged. Supplied without weights.

Constructed from a solid wood block, 15 slotted holes accomodating tubes up to 13 mm in dia.
