Consider a rectangular block of metal of height A, width B, and length C, as shown in FIGURE 21-39. If a potential difference V is maintained between the two A Ã— 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 Ã— C faces of the block. Give your answer in terms of IAB.
