Question

Define resistivity of a material. Derive its expression. Write its S.1 unit​

Answer 1

Answer:

Resistivity of the material is defined as the resistance offered to current flow by a conductor of unit length having unit area of cross-section. Unit is ohm-metre(Ωm). ρ=lRA ; where A=1 m2 and l=1 m. Answer verified by Toppr. Upvote (0)
