13. Consider the circuit above. Two identical bulbs and a capacitor are connected to an ideal 3 Volt
battery. The capacitor is initially uncharged. Just after the switch is closed, what are the voltage
differences across bulb A, bulb B, capacitor C, and the battery?

14. A circular loop of wire moves away from the north pole of a bar magnet as shown in the figure
above. What is the direction of the induced current in the wire in the upper portion of the loop, and
the direction of the magnetic field generated by the induced current?

15. A loop of wire moves into a region with a magnetic field as show above. What is the direction of the
current induced into the wire? What is the direction of the magnetic field generated by the loop in
the center of the loop?
