Resistivity of Materials – Definition, Formula and Derivation

Resistivity of Materials – Definition, Formula and Derivation

Resistivity of a material is defined in terms of measurement of the electric field (E) across it that generates current density (J). The formula for resistivity is given by, ρ = E /J, and. R = ρ L/A. Where ρ is the proportionality constant known as the resistivity of the material which is the characteristic property of each material.
