Question

on what factors resistance may depend and define electric resistivity

Answer 1

Electric resistance depends on the following factors-

1)Length of the wire.

2)Cross sectional area of the wire.

3)Material from which the wire is made from.

4)Temperature

Electric Resistivity-

Electrical 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.

Resistance=  ρ x Length/Area

Here, ρ is the resistivity.
