Question

Define the term ‘electrical conductivity’ of a metallic wire. Write its S.I. unit.
Can anyone explain this question!​

Answer 1

Answer:

The conductivity of a metallic wire is defined as the degree to which a specified material conduct electricity calculated as the ratio of current density in the material to the electric field which causes the flow of current, The SI unit of conductivity is ohm-1 metre-1 or mho metre-1 or siemen metre-1

Answer 2

Answer:

The electrical conductivity of a metallic wire is defined as the measure of a material's ability to allow the transport of an electric charge.
