Birds resting on high-voltage power lines are
a common sight. A certain copper power line
carries a current of 45.3 A, and its resistance
per unit length is 4.89 × 10−5
/m.
If a bird is standing on this line with its feet
7.4 cm apart, what is the potential difference
across the bird’s feet? Answer in units of V.
