A material's electrical resistivity is a measure of how strongly it opposes the flow of current. The ohm meter (m) is the SI unit of electrical resistivity. The Greek letter rho is commonly used to represent it. Conductors are materials that easily conduct current and have a low resistivity.
resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents. High resistivity designates poor conductors.
