Step-by-step explanation:

The relation between resistance and resistivity is given by :


R=\rho (l)/(A)


\rho is resistivity of material

l is length of wire

A is area of cross section of wire

Resistivity of a material is the hidden property. If one wire has 3 times the length of the other, then it doesn't affect its resistivity. Hence, the resistivity of two wires is
