Resistivity

 

(or specific resistance), a physical quantity equal to the electrical resistance of a cylindrical conductor of unit length and unit cross-sectional area. Designated p, resistivity is usually expressed in ohm-centimeters or ohm-meters.

electrical resistivity, specific resistance

The resistance, in ohms, of an electric conductor of unit cross-sectional area and unit length.
