Find the length of an aluminum wire with a cross section of 10 mm2 so that the resistance is 0.032 Ohm.

The resistance of an aluminum wire can be calculated using the formula:
R = ρ * l / S, where R is the resistance of the aluminum wire (R = 0.032 Ohm), ρ is the resistivity of aluminum (ρ = 2.7 * 10 ^ -8 Ohm * m), l is the length of the aluminum wire (m) , S is the cross-sectional area of the aluminum wire (S = 10 mm ^ 2 = 10 * 10 ^ -6 m).
Let us express and calculate the length of the aluminum wire:
l = R * S / ρ = (0.032 * 10 * 10 ^ -6) / (2.7 * 10 ^ -8) = 11.85 m.
Answer: The length of the aluminum wire is 11.85 m.
