Resistivity
(redirected from Table of resistivities)

   Also found in: Dictionary/thesaurus, Wikipedia 0.01 sec.

resistivity

Electrical resistance of a conductor of unit cross-sectional area and unit length. The resistivity of a conductor depends on its composition and its temperature. As a characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric current. As temperature increases, the resistivity of a metallic conductor usually increases and that of a semiconductor usually decreases.


resistivity [‚rē‚zis′tiv·əd·ē]
(electricity)

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

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.
