A copper wire of radius a = 0.234 mm has an aluminum jacket of outer radius b=0.318 mm. There is a current i = 2.05 A in the composite wire. Take the resistivity for copper and aluminum to be 1.69 x 1080-m and 2.75 x 10 80-m. Calculate the current in (a) th copper and (b) the aluminum. (c) If a potential difference V = 16.3 V between the ends maintains the current, what is the length in meters of the composite wire?
