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
