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 rho = 1.50 10-2 ω·m, and the unit of length in the drawing is l0 = 5.80 cm. each piece of material is connected to a 3.00-v battery. find (a) the resistance and (b) the current in each case.
