Consider a rectangular block of metal of height A, width B, and length C. as shown in the figure below.

Consider a rectangular block of metal of height A, width B, and length C. as shown inthe figure below. If a potential difference V is maintained between the two A×B faces ofthe block, a current IAB is observed to flow. Find the current IBC that flows if the samepotential difference V is applied between the two B×C faces of the block (assume youknow A, B and C). Give the current IBC as a function of IAB.
