Homework Statement



Consider a rectangular block of metal of height A, width B, and length C, as shown in the figure below. If a potential difference V is maintained between the two A B faces of the block, a current IAB is observed to flow. Find the current that flows if the same potential difference V is applied between the two B C faces of the block. Give your answer in terms of IAB. (Use Iab for IAB, and A, B, and C, as necessary.)
