Difference Between Resistance And Resistivity
The difference between resistance and resistivity is discussed in the table below,
Resistance | Resistivity | |
---|---|---|
Definition | The property of the material that opposes the flow of the electric current in any material is called the resistance of that material. | The electrical resistance of any object that is 1 m long and has a 1 m2 is called as the resistivity of that material. |
Symbol | It is denoted by the symbol R | It is denoted by the symbol ρ |
Formula |
The formula for the resistance is, R = V/I |
The formula for the resistivity is,
|
SI unit | The SI unit of resistance is Ohm(Ω) | The SI unit of resistivity is Ohm-m(Ω-m) |

Electrical Resistance
Electrical resistance is the obstruction offered by the material in the flowing of the current or charge through the material. Thus, the higher the resistance the lower the amount of current passing through it. It is the property of a material that tells us about the flow of the current through the material. The substances that easily conducts the electric current are called conductors and they have very low electrical resistance, on the contrary, the substance that does not easily conducts the electric current are called insulators and they have very high resistance.
In this article, we will learn about, electrical resistance, its formula, factors affecting electrical resistance, and others in detail.
