Answer: The si unit of resistivity is ohm.
Resistance is a measure of the opposition to current flow in an electrical circuit. Materials resist electrical current flow. Resistivity is actually a figure that can allow a comparison of how different materials allow or resist current flow.
The si unit of resistivity is
The si unit of resistivity is ohm. The SI unit of resistivity of any substance is given by Ohm-metre (Ωm).
