Apply the rules and concepts of the Resistance and Resistivity to find out the Resistance in the following case: Suppose a rectangular block of iron has dimensions of 1.0 cm x1.0 cm x 10 cm. A potential difference is to be applied to the block between parallel sides and in such a way that those sides are equipotential surfaces (as in Figure given below). Figure What is the resistance of the block if the two parallel sides are, (1) The square ends (with dimensions 1.0 cm x 1.0 cm) and (2) Two rectangular sides (with dimensions 1.0 cm x 10 cm)? Hint: The value of resistivity ρ for iron is given by 9.68 x 10-8 Ω.m
