What is electrical resistivity?

Electrical resistivity is a measure of how well a material resists the flow of an electric current. A material with a high electrical resistivity is a poor conductor of electricity, while a material with a low electrical resistivity is a good conductor of electricity. This property is typically expressed in units of ohms × meters (Ω × m). Recall that ohms (Ω) are a unit of resistance (see “Physical and Theoretical Chemistry”).
