Electrical resistivity (also called specific electrical resistance or volume resistivity) is a fundamental property of a material that measures how strongly it resists electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-meter(Ω⋅m). For example, if a 1 m solid cube of material has sheet contacts on two opposite faces, and the r… Common symbols: ρ In SI base units: kg⋅m³⋅s−3⋅A−2 Derivations from other quantities: ρ, =, R, A, ℓ, {\displaystyle \rho =R{\frac {A}{\ell }}} SI unit: ohm meter (Ω⋅m)
