Question

explain the resistivity ​

Answer 1

Answer:

Electrical resistivity and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ.

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

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