Halliday, Resnick & Walker β Circuits: Problem 41
41 A copper wire of radius a = 0.250 mm has an aluminum jacket of outer radius b = 0.450 mm. There is a current i = 2.00 A in the composite wire. Using Table 26-1, calculate the current in (a) the copper and (b) the aluminum. (c) If a potential difference V = 12.0 V between the ends maintains the current, what is the length of the composite wire?
