physical quantity and property of material; inverse of the electric conductivity
AI overview
Electrical resistivity is a measure of how strongly a material opposes the flow of electric current through it—essentially the inverse of how easily electricity can pass through that material. It matters because different materials have vastly different resistivities, which determines whether they're useful as conductors (like copper wiring), insulators (like rubber), or semiconductors (like silicon in electronics).
