resistivity
Material's opposition measure
Resistivity is a measure of how strongly a material opposes the flow of electric current—the intrinsic resistance of a substance independent of its shape or size.
Materials with low resistivity (copper, silver) conduct electricity well; those with high resistivity (rubber, glass) resist it.
Engineers use resistivity to select materials for wiring, insulation, and semiconductors.
