| Resistance | Resistivity |
| The electrical resistance of an object is a measure of its opposition to the flow of electric current. |
Resistivity is the characteristic property of the material by which it resists the amount of current through it.
|
| It depends upon the length, area of cross-section and nature of the material of the given material, and physical conditions like temperature. |
It only depends upon the nature of the material and physical conditions like temperature.
|
| Its SI unit is ohm | Its SI unit is ohm meter. |
| It is denoted by R. | It is denoted by ρ (rho) |
