Question

define restivity of a conductor and its formula I will mark brainliest​

Answer 1

Answer:

Resistivity is equal to its resistance if it has unit length and unit area.

Resistivity = R*A/l

Hope it helps...Mark as brainliest as you have promised

Answer 2

the resistivity of a material is the resistence of a wire of the material of unit length and unit cross-sectional area....the resistivity of a metallic comductor increase with an increase in its temperature,wherase the reaistivity of a semi-conductor decrease with an increase in its temperature..

the s.I unit of electrical resistivity is the ohm.meter
