Chapter 6.3, Problem 2aT
Suppose an uncharged capacitor is connected in series with a battery and bulb as shown.
-
1. Predict the behavior of the bulb when the switch is closed. Explain.
Set up the circuit and check your prediction. If your prediction is in conflict with your observation, how can you account for your observation?
-
2. Without using a voltmeter, determine the potential difference across the capacitor at the following times:
• just after the switch is closed. Explain how you can tell. (Hint: Compare the brightness of the bulb to the brightness of a bulb connected to a battery in a single-bulb circuit without a capacitor.)
• a long time after the switch is closed. Explain how you can tell.
Use a voltmeter to check your predictions. (Hint: Be sure to discharge the capacitor completely after each observation.)

- Two long, straight conducting wires with linear mass density A are suspended from cords so that they are each horizontal, parallel to each other, and a distance d apart. The back ends of the wires are connected to one another by a slack, low-resistance connecting wire. A charged capacitor (capacitance C) is now added to the system; the positive plate of the capacitor (initial charge +Qo) is connected to the front end of one of the wires, and the negative plate of the capacitor (initial charge-Qo) is connected to the front end of the other wire (see the figure (Figure 1)). Both of these connections are also made by slack, low-resistance wires. When the connection is made, the wires are pushed aside by the repulsive force between the wires, and each wire has an initial horizontal velocity of magnitude vo. Assume that the time for the capacitor to discharge is negligible compared to the time it takes for any appreciable displacement in the position of the wires to occur.
