Abird lands on a bare copper wire carrying a current of 51 a. the wire is 8 gauge, which means that its cross-sectional area is 0.13 cm2. (a) find the difference in potential between the bird's feet, assuming they are separated by a distance of 5.1 cm.

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire
