Question

distinguish between resistance and resistivity in making a chart in 3 points​

Answer 1

resistivity the resistivity of a substance is numerically equal to the resistance of a road of that substance which is one metre long and one is complete and cross section .
please note that resistivity of a substance does not depend on its length of thickness its depends on the nature of the substance and temperature .
the SI unit of resistivity is ohm-meter .

resistance the property of a conductor due to which it opposes the flow of a current through it is called resistance .
the resistance of a conductor depend on length thickness nature of a material and temperature of the conductor .
the SI unit of resistance is ohm.
