Birds resting on high-voltage power lines are a common sight. The copper wire on which a bird stands is 2.0 cm in diameter and carries a current of 53 A. If the bird's feet are 3.9 cm apart, calculate the potential difference between its feet. (The resistivity of the wire is 1.7 x 10-8 n · m) Birds resting on high-voltage power lines are a common sight.
