उत्तर
| Electrical resistance | Resistivity |
| It is the property of the material due to which it opposes the flow of electricity through the conductor. | The resistivity is defined as the resistance of a material of 1 metre length and 1 square metre area of cross-section. |
| The SI unit of electrical resistance is the ohm. | The SI unit of resistivity is ohm-meter. |
| It is represented by the symbol R. | It is represented by the symbol ρ. |
| It depends on length, cross-sectional area of the conductor, and temperature. | It depends on the temperature and the material of the conductor. |
