What is the electrical resistance of a 10m copper wire with a cross section of 0.1mm ^ 2? The specific electrical resistance of copper is 0.017 Ohm mm ^ 2.
Given: l (the length of the copper wire taken) = 10 m; S (cross section of copper wire) = 0.1 mm2.
Reference values: according to the condition ρ (specific electrical resistance of copper) = 0.017 Ohm * mm2 / m.
You can determine the required electrical resistance of a copper wire using the formula: R = ρ * l / S.
Calculation: R = 0.017 * 10 / 0.1 = 1.7 Ohm.
Answer: The taken copper wire has a resistance of 1.7 ohms.
