## resistivity

- 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 ohmsSymbol: ρ Former name: specific 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.
