Question

here's a and b are of equal lengths different cross-section areas and made of the same metal first name the property which is same for both the wires second name the property which is different for both the wires third if the resistance of wire a is four times the resistance of wire b calculate first the ratio of cross section between areas of the wires and second the ratio of the radii of the wires​

Answer 1

Answer:

calculated

Explanation:

This is due to the reason that the resistivity is the property of the material of which the wire is made. As both the wires are made of the same metal, their resistivity is the same. (ii) Resistance. As both the wires are of different cross-sectional area, their resistances are different (r∝1/A).
