A bird lands on a bare copper wire carrying a current of 53 A. Thewire is 8 gauge, which means that its cross-sectional area is 0.13cm2.
(a) Find the difference in potential between the bird's feet,assuming they are separated by a distance of 4.3 cm.
_____________ mV
(b) Will your answer to part (a) increase or decrease if theseparation between the bird's feet increases? Explain.
