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

Answer»

Definition and SI unit of conductivity

The conductivity of a material equals the reciprocal of the resistance of its wire of unit length and unit area of cross section.

Alternatively :

The conductivity (σ) of a material is the reciprocal of its resistivity (ρ)]

(Also accept σ = 1/ρ)

Its SI unit is

(1/ohm-metre)/ohm^-1m^-1/(mhom^-1)/siemen m^-1

Detailed Answer :

Conductivity of a metallic wire is reciprocal to its resistivity i.e σ = 1/ρ and it is measured in Ω^-1m^-1or mho.m^-1
