ESAW Higher Range Rheostat for Electrical Engineering Lab (EEC-9844)

Specifications are same as given on page 35, the only difference is that imported bare Eureka Wire is replaced with Kanthal wire {having high stability and strength) is wound on a thick wall porcelain/cement pipe having a deeply grooved outer surface to provide air conducts for convection cooling. Contact with Kanthal resistance wire is made by two copper brushes having large contact area to give smooth current control and very little. The slider moves the full length of the Rheostat, moves rapid with ease.
