A bird sitting on a bare high voltage wire is not electrocuted because
there is no electrical potential difference across its body.
of the high resistance of its body.
the high voltage across its feet produces a small current.
its body is at a low electrical potential compared to the wire.

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?...
IP A bird lands on a bare copper wire carrying a current of 35 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 4.0
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
005 10.0 points Birds resting on high-voltage power lines are a common sight. The copper wire on which a bird stands is 2.78 cm in diameter and carries a current of 58 A If the bird's feet are 7.66 cm apart, what is the potential difference across its body? Copper's resistivity is 1.68 x 10 S2m. Answer in units of uV. 006 10.0 points A length of metal wire has a radius of 0.001 m and a resistance of 0.09...
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.
Birds resting on high-voltage power lines are a common sight. The copper wire on which a bird stands is 1.49 cm in diameter and carries a current of 22 A. If the bird’s feet are 9.3 cm apart, what is the potential difference across its body? Copper’s resistivity is 1.68 × 10−8 Ω m . Answer in units of µV
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 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...
2.[1pt Electrical power is typically transmitted over long distances at very high voltage, up to 1000 kV (for reasons that we will explore in the next problem). Suppose that bird a lands on a power line carrying 2690A, as seen in the figure below If the line has 3.08x10Ohm resistance per meter and the bird's feet are 3.60cm apart, what is the magnitude of the potential difference between the bird's feet? Answer: Incorrect, tries 2/6 Hint: Simple enough to calculate...
Suppose you fall from a building and on the way down you grab a high voltage wire. Assuming that the wire holds you, will you be electrocuted? If the wire breaks, should you continue to hold on as you fall?
