Mounted Resistance Coils

A Useful Apparatus For Showing How Resistance Varies With The Type Of Wire, Its Length And Diameter. The Apparatus Can Be Used With Wheatstone Bridge Or A Suitable Ohm-Meter. Lengths And Diameters Of Wires Are In 2:1 To Simplify Computations. A Set Of Five Collinear Coils Wound On Identical Bobbins And Mounted On Molded Base With 4Mm Sockets To Facilitate Electrical Connections. The Coils Are: 1 Copper, 32Swg, 10Mtr 2 Copper, 38Swg, 10Mtr 3 Copper, 32Swg, 20Mtr 4 Copper, 38Swg, 20Mtr 5 Nichrome, 38Swg, 10Mtr. (Mounted Resistance Coils)
