The resistance and the magnitude of the current depend on thepath that the current takes. The drawing shows three situations inwhich the current takes different paths through a piece ofmaterial. Each of the rectangular pieces is made from a materialwhose resistivity is ρ = 1.50 x 10-2Ω*m, and the unit of length in the drawing isL0 = 3 cm. Each piece of material is connectedto a 3.00-V battery. Find (a) the resistance and(b) the current in each case.
