Please help me solve the following.I answered it correctly, but have since forgotten the formula. Will be determining the cable's cross-sectional area, and the power loss.

A power plant is being built that will deliver 400 kW at 79,000 V using a tungsten cable with a resistance of 0.004 N. The cable will span 5500 m. Resistivity (A-m) Material Aluminum 2.65 x 10 8 Copper 1.68 x 10-8 Gold 2.44 x 10-8 A = .077 m^2 Iron 9.71 x 10-8 power loss = 1025 W Platinum 10.6 x 10 8 Silver 1.59 x 10 8 Tungsten 5.60 x 10-8
