what will be the ratio of three resistances if the mass of three copper wires is in the ratio 1:3:5 and their lengths are in the ratio 5:3:1?

Expert Answer:

resistance of a substance is proportional to the length when the cross sectional area is same...It will not depend upon the mass of the substance.
