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 102 2*m, and the unit of length in the drawing is Lo = 4 cm. Each piece of material is connected to a 3.00-V battery. Find (a) the resistance and (b) the current in each case. 4LO 2LO 210 Lo 4Lo 4Lo
