Unformatted text preview: Answer Problems 1 through 3 directly on the test page, not in the blue book. Problem 1 (5 pts) You connect a battery, a lightbulb, and an uncharged capacitor together with copper wires in series. Which of the following statements about the connected circuit are correct? For each statement circle T or F : T F Electrons flow across the gap between the plates. T F The current in the circuit increases with time. T F The magnitude of charge on each plate of the capacitor increases with time. T F The fringe field of the capacitor increases with time. T F The net electric field inside the copper wires increases with time. Problem 2 (10 pts) Some coils not shown in the diagram make a nearly uniform magnetic field of magnitude 1.3 T in the 8 cm by 4 cm shaded region, with little magnetic field elsewhere. The wire is pushed outward, out of the page toward you (in the +z direction). x y z 8 cm 4 cm 15 A (a, 5 pts) In the shaded region, what is the direction of the magnetic field made by the coils? Circle the(a, 5 pts) In the shaded region, what is the direction of the magnetic field made by the coils?...
