Nichrome wire can be used as an alternative to platinum wire for flame testing by colouring the non-luminous part of a flame to detect cations such as sodium. The reason resistivity is defined this way is that it makes resistivity an intrinsic property, unlike resistance all copper wires, irrespective of their shape and size, have approximately the same resistivity, but a long, thin copper wire has a much larger resistance than a thick, short copper wire. Electrical conductance conductivity of metal semiconductor and insulator | band theory conductance properties of conductor resistivity parallel series resistances. The softness of copper partly explains its high electrical conductivity copper wire is used in power generation, power transmission, power distribution. The ohmmeter was a risk since it produced a small electric current holding or touching the length of wire being measured was avoided rubber soled shoes were worn at all.
