Birds resting on high-voltage power lines are a common sight. The copper wire on which a bird stands is 1.94 cm in diameter and carries a current of 112 A. If the bird's feet are 9.18 cm apart, what is the potential difference across its body? Copper's resistivity is 1.68 x 10-822 m. Answer in units of 4V.

A current of 75.7 mA exists in a metal wire. How many electrons flow past a given cross-section of the wire in 9.4 min? The fundamental charge is 1.602 Times 10^-19 C. Birds resting on high-voltage power lines are a common sight. A certain copper power line carries a current of 122 A, and its resistance per unit length is 2.39 Times 10^-5 1 Ohm/m. If a bird is standing on this line with its feet...

A bird lands on a bare copper wire carrying a current of 27 A . The wire is 8 gauge, which means that its cross-sectional area is 0.13 cm2. Find the difference in potential between the bird's feet, assuming they are separated by a distance of 5.0 cm . Express your answer using two significant figures I got the answer .00174, but it is incorrect. I used the equation V=IR and substituted R for p(L/A)

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?...
