Birds resting on a high-voltage power lines are a common sight. A certain copper power line carries a current?
Birds resting on a high-voltage power lines are a common sight. A certain copper power line carries a current of 46.3 A, and its resistance per unit length is 1.22 x10^-5 /m. If a bird is standing on this line with its feet 4.0 cm apart, what is the potential difference across the bird's feet?
Essentially zero. Figure it out if you wish. Use v = iR. And for R it's the resistance per meter times the length (.04m)
