A bird lands on a bare copper wire carrying a current of 27 A . The wire is 8 gauge, which means that its cross-sectional area is 0.13 cm2.
Find the difference in potential between the bird's feet, assuming they are separated by a distance of 5.0 cm .
Express your answer using two significant figures
I got the answer .00174, but it is incorrect. I used the equation V=IR and substituted R for p(L/A)
