Question

define resistivity?​

Answer 1

Explanation:

Resistivity is a measure of the resistance of a given size of a specific material to electrical conduction ....

Answer 2

$\Huge\bf\purple{\mid{\overline{\underline{Answer}}}\mid}$

Resistivity is a materialistic property determining the resistance of conductor. It only depends upon the nature of material and doesn't depend upon the dimensions of the conductor (like length and area of cross-section).

It is represented as follows :-

$\boxed{\fbox{ \pink{resistivity = \rho}}}$

The basic definition of Resistivity is :-

It is numerically equal to the resistance of a conductor having unit length and unit area of cross-section .

The SI unit of Resistivity is Ohm-meter

$\dashrightarrow{ \underline { \purple{SI \: unit = \: \Omega \: m}}}$
