Solve the all parts of given question:
Question: 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 10-2 omh•m, and the unit of length in the drawing is L0 = 5.49 cm. Each piece of material is connected to a 3.00-V battery.
Part A: Find the resistance?
Part B: Find the current in each case?
