A rectangular block of iron has dimensions 1.2 cm x 1.2 cm x 15 cm. A potential difference is applied between the parallel sides. Calculate the resistance of the block if the two parallel sides are formed by (a) square ends with dimensions 1.2 cm x1.2 cm (b) two rectangular ends formed with dimensions 1.2 cm x 15 cm
