the reciprocal of resistance is called resistivity or specific resistivity and its unit is ohms metre and

and resistance is a to oppose the electric current so its reciprocal is a resistivity or specific resistivity please markers brand list

Electrical resistivity (also called specific electrical resistance or volume resistivity) and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (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.
