Define resistivity and state its si unit.Does it vary with temperature
Answers
Electrical resistivity (also known as specific electrical resistance, or volume resistivity) is a fundamental property of a material that quantifies how strongly that material opposes 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] As an 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...it varies from temperature to temperature.....plzzz mark me Brainliest
It is the ability of a given material to resist the flow of charges in a certain temperature. SI unit: Ohm m
Yes it changes with change in temperature.
