smaller currentthan the latter for a given magnetizing force, but at thesame time have a greater resistance. On reflection it willbe observed that a best winding exists for each set ofconditions, which winding results in the greatest transmis-sion distance for lines of given cross-section. The… … A (2) which takes no account of bedding of wires in precedinglayers or of interleaving insulation. If D be the wirediameter in mils, and z be the mean length of a turn in SIMPLEX TELEGRAPHY 17 inches, the resistance of the copper wire forming the wind-ing will be Rr = ^-^ ohms (3) at 20° cent.,…
