The resistance and the magnitude of the current depend on the path that the current takes. The drawing shows three situations in which the current takes different paths through a piece of material. Each of the rectangular pieces is made from a material whose resistivity is p - 1.50 x 1022m, and the unit of length in the drawing is Lo-7 cm. Each piece of material is connected to a 3.00-V battery. Find (a) the resistance and (b) the current in each case. 240 (a) 410 210 Alo (b) 200 (e) 410
