Copper wire resistance ohms
http://hyperphysics.phy-astr.gsu.edu/hbase/Tables/rstiv.html WebMar 28, 2024 · In the attached table, for AWG 16 the (single) cable should have a copper cross section of 1.3 mm2 and a resulting electric resistance of 4 mili-ohm per ft. Therefore, by connecting the two wires at one end and measuring the resistance at the other end, like I did in the second picture, I should have read 4 x 200 = 800 mili-ohm = 0.8 ohm.
