Resistance cores also termed rheostats or diverter coils consist of long strips of iron ribbon and are constructed in two forms - the panel form, insulated with asbestos between each layer; the other form is cylindrical, and the layers of the coil are separated by mica and asbestos insulation. Both mica and asbestos, being capable of standing high temperature, are valuable insulating ma terials, preventing the coils from being short-circuited and securing full resistance. When resistance fails or lessens, the current, instead of following its proper path, is carried to ground through a shorter course.
