Diff. Between resistance and resistivity. |
| Answer» \tResistanceResistivity1. Resistance of a conductor is the the obstruction by the conductor in the flow of current through it. It is measured by the potential difference needed across the conductor to flow one ampere current through it.1. Resistivity the property of the conductor due to which it offers resistance to the flow of current throgh it. It is measured by the resistance offered by 1 m length of wire of that material of area of cross section 1 m2.2. The resistance of a conductor depends upon its material, temperature, length and area of cross section.2. Resistivity of the material depends only on its material and temperature.3. SI Unit of resistance is ohm3. SI unit of resistivity is ohm-metre.\t | |
