A maximum current of 60 A flows in a copper conductor with cross-sectional area, A̟ = 13.5 mm2 and a resistivity of 20 n. m. A 250 m cable is being used on a 240 V DC circuit to carry a current of 50 A. Assuming a maximum operating temperature of 70°C, calculate the following: 1. The power loss in the cable i1. The voltage at the load if the voltage at the service panel is 243 V.
