Find the current strength of a copper conductor at a voltage of 1V, 1000m long. S = 0.034.

Initial data: U (effective voltage at the ends of the copper conductor) = 1 V; l (copper conductor length) = 1000 m; S (cross-sectional area) = 0.034 mm ^ 2.

Constants: ρ (resistivity of copper) = 0.017 Ohm * mm ^ 2 / m.

1) Let’s calculate the resistance of a given copper conductor:

R = ρ * l / S = 0.017 * 1000 / 0.034 = 500 Ohm.

2) Calculate the current on the copper conductor:

I = U / R = 1/500 = 0.002 A = 2 mA.

Answer: The current on this copper conductor is 2 mA.
