ekorteweg R = 0,268908192 ohm per meter you can calculate: rho = 52.8 nΩ·m (at 20 °C) or 5,28E-08 ohm*meter (wikipedia) diameter = 0,5 mm --> r =0,25 mm = 0,00025 m the use: R = rho* (L div A) L = length A = area. R= 5,28E-08 * (1 div (PI* 0,00025^2)) = 0,269 ohm per meter length, so 10 meters gives 2,69 Ohm approx. "div" means "divide" since banggod text cannot handle the slash character... sorry. God bless Edgar
