Birds resting on high-voltage power lines are a common sight. The copper wire on which a bird stands is 2.39 cm in diameter and carries a current of 34 A. If the bird’s feet are 6.35 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.
