Resistance Coils, Shows how resistance varies with the type of wire, length of wire, and diameter of wire in coil in 0.1 to 0.9 ohms., Each

Details:

Can be used with a Wheatstone Bridge or Ohmmeter.Constantan coils non-inductively wound with double-silk On plastic rod held within a transparent plastic tubeTwo terminals; resistance values appear on coil Accuracy, 1%Wire lengths are in two to one ratio to simplify computations. Five coils are mounted on a base of size 8 x 5 in. and six binding posts facilitate hook-upThe coils are wound as follows :Wire SWG LengthCopper 22 10 metersCopper 28 10 metersCopper 22 20 metersCopper 28 20 metersCopper Nickel 22 10 metersOrder InfoIndividually packed
