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 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. T F Electrons flow across the gap between the plates. 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 correct direction.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
