Resistivity
|
The property of the conductor due to which it opposes a flow of
current through it is called resistance.
The SI unit of resistance is Ohm ( Ω )
The resistance of a conductor depends on its length and area of cross
section.
|
The resistivity of a conductor is the resistance of a conductor of
unit length and unit area of cross section.
The SI unit of resistivity is Ohm-metre (
The resistivity of a conductor
does not depend on its length and area of cross section.
