1. The problem statement, all variables and given/known data A bird sits on a high-voltage power line with its feet 2.0 cm apart. The wire is made from aluminum, is 3.0 cm in diameter, and carries a current of 160 A. What is the potential difference between the bird's feet? 2. Relevant equations I=neAv Where I is current, n is electrons per volume, A is cross sectional area, v is drift velocity. V=E*D 3. The attempt at a solution My answer is going to have units of J/C, and the cross sectional area of the wire is 1/4*Pi*(3cm)^2. I don't know where to proceed from here.
