Electrical resistivity, ρ\rhoρ, is a material property that quantifies how strongly a given material opposes the flow of electric current.
What are the correct SI base units for electrical resistivity?
kg m2s−3A−2\text{kg m}^2 \text{s}^{-3} \text{A}^{-2}kg m2s−3A−2
kg m3s−3A−2\text{kg m}^3 \text{s}^{-3} \text{A}^{-2}kg m3s−3A−2
kg m3s−2A−2\text{kg m}^3 \text{s}^{-2} \text{A}^{-2}kg m3s−2A−2
kg m3s−3A−1\text{kg m}^3 \text{s}^{-3} \text{A}^{-1}kg m3s−3A−1
