Answer: 182.45Ω
Step-by-step explanation:
Hi to answer this question we have to apply the next formula:
Resistance = ρL /A
Where:
ρ = resistivity of copper at 20° ( 1.68 x 10^-8 Ωm)
L = lenght
A = transversal area = π (diameter /2)^2 = π (8.252x10^-03 /2)^2 =
5.35 x10^-05
Since
1 mile = 1,609 meters
361 miles = 580,849 meters (length)
1 mm = 0.001 meter
8.252 mm = 8.252x10^-03 m (diameter)
Resistance = [ 1.68 x 10^-8 (580,849)]/(5.35 x10^-05) = 182.45Ω
