Resistivity



noun
1.
the power or property of resistance.
2.
Also called specific resistance. Electricity. the resistance between opposite faces of a one-centimeter cube of a given material; ratio of electric intensity to cross-sectional area; reciprocal of conductivity.
noun
1.
the electrical property of a material that determines the resistance of a piece of given dimensions. It is equal to RA/l, where R is the resistance, A the cross-sectional area, and l the length, and is the reciprocal of conductivity. It is measured in ohms ρ Former name specific resistance
2.
the power or capacity to resist; resistance
resistivity
(rē’zĭs-tĭv’ĭ-tē)
A measure of the potential electrical resistance of a conductive material. It is determined experimentally using the equation ρ = RA/l, where R is the measured resistance of some length of the material, A is its cross-sectional area (which must be uniform), and l is its length. It is measured in ohm-meters.
