Answer:
resistance of the given copper wire is 0.055 ohm
Explanation:
As we know that the resistance of the conductor is given as
[tex]R = \rho\frac{L}{A}[/tex]
here we know that
[tex]L = 1.5 miles = 2413.5 m[/tex]
[tex]diameter = 0.012 inch[/tex]
[tex]diameter = 0.03 cm[/tex]
now the resistance is given as
[tex]R = (1.68\times 10^{-8})\frac{2413.5}{\pi(0.015\times 10^{-2})^2}[/tex]
so we have
[tex]R = 0.055 ohm[/tex]
