An engineer is characterising the electrical properties of a newly synthesized thin-film semiconductor. They need to express the electrical resistivity, ρ\rhoρ, of the material in terms of S.I. base units.
Which of the following is the correct representation of the S.I. base units for resistivity?
kg m3 s−3 A−2\text{kg}\,\text{m}^3\,\text{s}^{-3}\,\text{A}^{-2}kgm3s−3A−2
kg m2 s−3 A−2\text{kg}\,\text{m}^2\,\text{s}^{-3}\,\text{A}^{-2}kgm2s−3A−2
kg m3 s−2 A−2\text{kg}\,\text{m}^3\,\text{s}^{-2}\,\text{A}^{-2}kgm3s−2A−2
kg m2 s−3 A−1\text{kg}\,\text{m}^2\,\text{s}^{-3}\,\text{A}^{-1}kgm2s−3A−1
