Length of conductor = 500m =500/1000 = 0.5km Therefore resistance of copper conductor = 2.25 x 0.5 =1.125 Ohms Similarly for Aluminium, The resistance per km for Aluminium is given by: R = 36/S(c.s.a) Again S = 10mmsq Hence R = 36/10 = 3.6 Ohms per km Length of conductor = 0.5km Therefore resistance of copper conductor = 3.6 x 0.5 = 1.8 Ohms How to calculate the electrical resistance of a wire, Click to share on Facebook (Opens in new window), Click to share on Twitter (Opens in new window), Click to share on Google+ (Opens in new window), Click to share on LinkedIn (Opens in new window), Click to share on Pinterest (Opens in new window), Click to share on Reddit (Opens in new window), Click to share on WhatsApp (Opens in new window), Click to email this to a friend (Opens in new window).
