Consider a rectangular block of metal of height A, width B, and length C , as shown in the figure. If a potential difference V is maintained between the two A X 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 X C faces of the block
The Attempt at a Solution
I thought this last equation was right, but apparently it isn't. When I entered it, it said that B, V, and rho had no impact upon the answer. I'm not really sure what to do now...
