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
Homework Answers
V = i R
V = i * rho * L / ( pi/4 * d^2)
V = 22* *1.68*10^-8* 0.093 / ( 3.14/ 0.0149^2)
V = 197.23 uV

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?...

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

Part 1 Before we can consider the effects it might have, we must consider the high tension power line itself. Such wires are frequently constructed by twisting aluminum or copper wires together into a large flexible bundle. Consider such a copper cable with a diameter of 4 cm. If this cable is 10 km long, what is its resistance? Remember: Resistance = Resistivity * Length / Area Resistivity of copper is 0.0000000168 Ω-m Cross sectional Area of...
