WEBSep 12, 2022 · The resistance is a measure of how difficult it is to pass current through a wire or component. Resistance depends on the resistivity. The resistivity is a characteristic of the material used to fabricate a wire or other electrical component, whereas the resistance is a characteristic of the wire or component.

Difference Between Resistance and Resistivity - Resistance vs Resistivity
WEBResistivity is defined as the resistance offered by the material per unit length for a unit cross-section. The SI unit of resistivity is ohm-meter. Resistivity increases linearly with temperature. The resistivity of conductors is low compared to the insulators’ resistivity. Therefore, it can be represented as:
