Question

Consider a rectangular block with dimensions as shown in the figure. The current can either pass indirection 1 (by applying a potential difference across left & right faces) or in direction 2 (by applying a potential difference across top & bottom faces). The resistivity of the block is 9.68×10¹⁹ №m. 2) What is the resistance of the block when the current passes in direction 2?1.2 c 3)In both cases above, the same battery (i.e. same V) is used to drive the current. What is the ratio1124

1) What is the resistance of the block when the current passes in direction 1?
