By saying that the resistivity of copper is 1.69 X 10^-8 Ω m , we mean that if
we take a rod of copper metal 1 m long and 1 m2
in area of cross section, then
its resistance will be 1.69 X 10^-8 Ω

Answer:
Length = 1km
= 1000 m
Radius = 1mm
= 1 × 10^-³
Resistivity of copper = 1.72 × 10^-8 Ω m
Resistance = Resistivity of copper × Length / Area
R = rho × L/A
R = rho × L / πr²
R = 1.72 × 10^-8 × 1000 / ( 22/7 × 1 × 10^-3)²
R = 5.5 ohm
