[QUOTE="Fiona, post: 490893, member: 32214"] A radial circuit feeds a 12Kw load with a two core copper cable 70.25m long.the csa of each core is 10mm squared and the load current is 40A ( pcopper=1.78×10 to the power of - 8 ohms m. Calculate the total cable resistance. The total voltage drop in the cable. The supply voltage at the load. The supply voltage. Power loss in the cable total power supply? [/QUOTE]
