Resistivity of a wire experiment results

WebStudents will be asked to look up the resistivity of the metal of their wire. It is useful to have a data book or internet access available (and to know the metal being used). Expected … WebHigh values of resistivity imply that the material making up the wire is very resistant to the flow of electricity. Low values of resistivity imply that the material making up the wire transmits electrical current very easily. The unit of resistivity is the ohm meter (Ω m). The resistivity ρ (rho) of a material is given by
