Question

What do you mean by resistivity of a substance? On which factor does it depends?​​

Answer 1

Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. ... A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents.

it depends on the nature of the material

Answer 2

Answer:

Resistivity of a substance is the resistance of a wire of that material of unit length and unit cross sectional area . it's unit is ohm meter . The resistivity of a substance depends on nature of substance and temperature of conductor .

Hope this helps you...........
