Electrical resistivity and conductivity - Wikipedia
WEBElectrical resistivity (also called volume resistivity or specific electrical resistance) is a fundamental specific property of a material that measures its electrical resistance or how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current.
Resistivity | Definition, Symbol, & Facts | Britannica
WEBResistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents. High resistivity designates poor conductors.

Resistivity | Definition, Calculation & Materials
WEBResistivity is a property of materials that describes their ability to resist the flow of electric current. It is defined as the resistance of a unit length of a material with a unit cross-sectional area. Resistivity is usually denoted by the Greek letter rho (ρ) and has units of ohm-meters (Ω·m).
