# resistivity

[ ree-zis-**tiv**-i-tee ]

## noun

- the power or property of resistance.
- 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.

resistivity

/ ˌriːzɪsˈtɪvɪtɪ /

## noun

- 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 namespecific resistance - 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.
