What is the resistance of a copper conductor with a length of 0.2 m and a cross section of 0.1 mm ^ 2

Data: l (copper conductor length) = 0.2 m; S (section) = 0.1 mm2; ρm (specific electrical resistance of copper; t = 20 ºC) = 0.017 Ohm * mm2 / m.

The resistance of the presented copper conductor: R = ρm * l / S = 0.017 * 0.2 / 0.1 = 0.034 Ohm = 34 mOhm.

Answer: The resistance of the presented copper conductor is 34 mΩ.
