1. Task  You will be shown four different arrangements of light bulbs connected to batteries with conducting wires. The arrangements will vary with their being between 0 and 4 light bulbs connected in series. Assume all pieces in the circuit behave perfectly. A voltmeter will be used to measure the potential difference between the terminals of the battery.

2. V1V1 V3V3 V2V2 V4V4

3. Rank the potential difference measured between the two battery terminals from the greatest to the least. If there are any ties indicate them. A. V 1 > V 2 > V 3 > V 4 B. V 4 > V 3 > V 2 > V 1 C. V 1 = V 4 > V 2 = V 3 D. V 2 = V 3 > V 1 = V 4 E. V 1 = V 2 = V 3 = V 4

4. What was the reason that you ranked them that way? A. The more resistors, the more voltage the battery supplies B. The more resistors the less voltage a battery supplies C. The voltage is used by the first light bulb, then the next … D. Ideal batteries always provide the same voltage E. Some other reason

5. How confident are you about your answer? A. I know I’m right B. I’m pretty sure C. Neutral D. I’m mostly guessing E. I’m completely guessing
