Answer:

ratio of their resistance is 2:1.

Explanation:

resistivity is the measure of resistance to electric current of a material .

resistivity is measured in ohm meter.

it is property of material.

resistance is an electrical device that resists the flow of electric current.

resistance is measured in ohm.

where, L is the length of the wire

r is the radius of wire

A is the cross section area of wire

R is the resistance
