Final answer:
To find the resistance of a 1.00-km length of 0-gauge copper wire with a diameter of 8.252 mm, use the resistivity formula with the known resistivity of copper and calculate the cross-sectional area from the diameter.
Explanation:
The question is concerning the resistance of electrical conductors, specifically the resistance of a 0-gauge copper wire used in power transmission.
To calculate the resistance of a 1.00-km length of 0-gauge copper wire with a diameter of 8.252 mm, one would use the resistivity formula R = ρL/A, where R is resistance, ρ is the resistivity of copper, L is the length of the wire, and A is the cross-sectional area of the wire.
Given the diameter (d = 8.252 mm), we can find the areaausing the formula A = π(d/2)^2. The resistivity (ρ) of copper at 20°C is typically around 1.68 x 10^-8 Ω·m. With these values, the resistance (R) can be found and expressed in ohms (Ω).
