WebFeb 2, 2024 · Resistivity ρ, unlike resistance, is an intrinsic property of a material.It means that it doesn't matter whether the wire is thick or thin, long or short. The resistivity will always be the same for a specific material, and the resistivity units are "ohm meter" (Ω × m).The higher the resistivity is, the more difficult it is for the current to flow through a wire. WebAug 15, 2024 · Over relatively small temperature changes (about 100 ∘ C or less), resistivity ρ varies with temperature change Δ T as expressed in the following equation. (8.4.2) ρ = ρ 0 ( 1 + α Δ T), where ρ 0 is the original resistivity and α is the temperature coefficient of resistivity.
