Difference Between Resistance and Resistivity

Difference between resistance and resistivity is explained here in detail. The concepts of resistivity and resistance is one of the most basic and crucial part of the topic of current and electricity. In this article, the main comparison and differences between resistance and resistivity in tabular form is given here in detail. These resistance and resistivity difference and comparison will help the students to get a detailed overview about them and have better understanding of the topics.

Before moving to their differences, it is important to know what resistance and resistivity is and other related details. Visit the links given below to know all the details about resistivity and resistance in detail.

Check the table given below for the detailed comparison and differences between resistivity and resistance.

Difference Between Resistance and Resistivity

Sl. No.

Differentiating Property





Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons.

Resistivity is the physical property of a particular substance which is having particular dimensions.



Resistance is directly proportional to the length and temperature while it is inversely proportional to the cross-sectional area of the material.

Resistivity is only proportional to the nature and temperature of the particular material.







R = V/I or,
R = ρ(L/A)

V = Voltage, I = Current, ρ = Resistivity

ρ = (R×A)/L

R = Resistance, L= Length, A = Cross-sectional area


SI Units

The SI unit of resistance is Ohms

The SI unit of resistivity is Ohms-meter.



The property of resistance is used in several places like heaters, fuses, sensors, etc.

Electrical resistivity measurement is used as a quality control test for calcareous soil.

These were the main resistance and resistivity differences that are crucial to understand. Questions based on resistivity and resistance is common in most exams and so, it is important to be thorough with these comparisons.
