Additional information
Electrical resistivity is a property of a material that quantifies its resistance to the flow of electric current. It measures how much a material opposes the movement of electric charges when subjected to an electric potential difference or voltage.
Unlike electrical resistance, which depends on the dimensions of a conductor, electrical resistivity is an intrinsic property that remains constant for a specific material regardless of its size or shape.
The standard unit for measuring electrical resistivity in the International System of Units (SI) is the ohm-meter (Ω·m).
