Question

Explain the terms i) Resistivity and ii) Conductivity and give its units

Answer 1

Resistivity means measuring of resisting power
of a specific material to the flow of an electric current.its unit is ohm- Meter. conductivity means the degree of a specific material conducts electricity,it is the ratio of current density in the material to the electric field.its unit is Siemens/meter

Answer 2

⭐ Hello Mate⭐
✔️Here is your answer ✔️
============✓✓✓✓✓=============

◆Resistivity◆

The resistivity of a material is the resistance offered by 1m length of the wire of the material, having area of cross section 1 m².
The factors affecting the resistivity are-
1= Nature of the material.
2= Temperature of the material.
●Unit of resistivity●
The SI unit of resistivity is Ohm- metre.

◆Conductivity◆

The ability of a metal to conduct or flow electricity is known as conductivity. Electric current can easily flow in metals as metals are the good conductor of electricity and this property is known as conductivity.
●Unit of conductivity●
The SI unit of conductivity is Siemens per metre.
