Electric resistivity (ρ) is a fundamental property of materials that quantifies how strongly a material opposes the flow of electric current. It is the reciprocal of electrical conductivity.
The SI unit of resistivity is the ohm-meter (Ω·m). Materials with high resistivity are good insulators, while materials with low resistivity are good conductors.
