Answer 1

${\huge{\blue{\texttt{\orange A\red N\green S\pink W\blue E\purple R\red}}}}$

Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. ... Thus, in the metre-kilogram-second system, the unit of resistivity is ohm-metre.

Answer 2

Answer:

Resistivity, electrical resistance of a conductor of unit cross sectiional area and unit lenghth.

The unit of resistivity is ohm meter.

Explanation:

The resistivity of a material depends on it's nature and the temperature of the condutor ,but not it's shape and size.
