Three Wires of the Same Diameter and Length Are Made

Multiple Choice

Three wires of the same diameter and length are made from three different metals: copper (ρ​ = 1.7 × 10^-8 Ω·m) ,aluminum (ρ​ = 2.7 × 10^-8 Ω·m) ,and silver (ρ​ = 1.6 × 10^-8 Ω·m) .Which wire has the least resistance?

A) the aluminum wire
B) the silver wire
C) the copper wire
D) Since insufficient information is given to find the resistance of each wire,one cannot find the answer.
