A bird rests on a high voltage aerial power line with the current 100A.The wire diameter is 20mm, and the bird feet are 10cm apart. What should be the resistivity of the wire material to produce potential difference 10V between bird feet? mΩ*m
PLEASE the answer is not 0.314 or 0.00314 and it should be in mΩ*m unit

A typical overhead power line is bare wire at a high potential relative to ground. A local line receives power at 3300 V with respect to the ground; the delivered voltage is slightly less, due to resistance loss in the wire. The wire is 10 km long, carries a current of 60 A, and has a resistance (made small to limit power loss) of 2.5 Ω. 1) Approximately how much power is lost due to the resistance of the wire?...
