MOUNTED RESISTANCE COILS
(0713) |
A useful apparatus for showing how resistance varies with the type of wire, length of wire and. diameter of wire in coils. The apparatus can be used with wheatstone bridge or a suitable ohm-meter. Lengths and diameters of wires are in two to one ratios to simplify computations. A set of five collinear coils wound on identical bobbins and mounted on anodized aluminium sheet with six 4mm sockets to facilitate electrical connections. |
