Aluminum Brass A rectangular cross section wire is made using aluminum o = 3.5 x 10?Slm and brass o = 1.6 x 10'Slm as shown in the figure. The dimensions are a = 3mm and b = 5mm. A DC current of 8A is flowing through 1km of this wire. Assume that the current density at each section of the wire is homogeneous. a. Find the resistance of the aluminum part of the wire. 1 km 2a/3 a/3 Ra= X 12 b. Find the resistance of the brass part of the wire. R= X 2 c. Find the total resistance of the wire. R = X 12 d. Find the potential difference between the two ends of the wire. V = X V
