Define the term electrical conductivity of a metallic wire. Write its SI unit.

Define the term 'conductivity' of a metallic wire. Write its SI unit.

(a) Define the term 'conductivity' of a metallic wire. Write its SI unit. (b) Using the concept of free electrons in a conductor, derive the expression for the conductivity of a wire in te'rms of number density and relaxation time. Hence obtain the relation between current density and the applied electric field E.
