Consider current flowing through the unit cube of material shown to the right resistivity is defined as the voltage measured across a unit cubes length (volts per metre, or v/m) divided by the current flowing through the unit cubes cross sectional area (amps per meter squared, or a/m 2). this results in units of ohm-m 2 /m or ohm-m.
