A crow sits on a 2 cm diameter copper (p= 1.67 x 10 m) wire, which carries a current of 70 amps. If the bird's feet are 11 cm apart, find A) the potential difference between the bird's feet. B) If the bird ate away the wire's insulation, how much current would flow through the bird, whose resistance is 0.4 MS?
