What kind of inductors are used on machinesintended for high voltage and moderate current? Ans. The winding is composed of what is called magnet wire,with double or triple cotton insulation. Ques. Where considerable cross section is requiredhow is a wire inductor arranged? Ans. In order that the coil may be flexible several smallwires in multiple are used instead of a single large wire. TTAUKIXS ELECTRICITY Ques. How is the insulation arranged on inductorsof this kind? Ans. Bare wire is used for the wires in parallel, insulationbeing wrapped around them as in fig. 1,510. This construction reduces the space occupied by the wires, and theinsulation serves to hold them in | INSULATION.
