Question

what is electrical resistivity of metal? what is it's unit​

Answer 1

Answer:

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 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).[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.

Answer 2

Answer:

ohm-metres

The SI unit of electrical resistivity is expressed in ohm-metres (Ωm). It is also found in units of (μΩcm). Insulators have high values of electrical resistivity in the range of 1010 Ωm or more, whereas metal conductors have very small resistivity values in the range of 10-8 Ωm.
