## Electrical resistivity and conductivity |

**electrical resistivity**(also called**specific electrical resistance**or**volume resistivity**) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts . a low resistivity indicates a material that readily allows electric current. resistivity is commonly represented by theelectric current greek letter *ρ*( ). therho unit of electrical resistivity is thesi -ohm (Ω⋅m).meter ^{[1]}^{[2]}^{[3]}for example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m.**electrical conductivity**or**specific conductance**is the reciprocal of electrical resistivity. it represents a material's ability to conduct electric current. it is commonly signified by the greek letter σ ( ), but κ (sigma ) (especially in electrical engineering) and γ (kappa ) are sometimes used. the si unit of electrical conductivity isgamma persiemens (s/m).metre - definition

**Electrical resistivity** (also called **specific electrical resistance** or **volume resistivity**) and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts *ρ* (^{[1]}^{[2]}^{[3]} For example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m.

**Electrical conductivity** or **specific conductance** is the reciprocal of electrical resistivity. It represents a material's ability to conduct electric current. It is commonly signified by the Greek letter σ (
