Explanation / Answer

here,

diameter , d = 0.65 cm = 6.5 * 10^-3 m

L = 6.5 m

V = 16 V , current , I = 15 A

let the resistivity of wire be p

resistance , R = p * l /area = V/I

p * 6.5 /( pi * (6.5 * 10^-3 /2)^2) = 16 /15

solving for p

p = 5.45 * 10^-6 ohm.m

the resistivity of copper is 5.45 * 10^-6 ohm.m
