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 V1 V2 V3 V4

3 Rank the potential difference measured between the two battery terminals from the greatest to the least. If there are any ties indicate them. V1 > V2 > V3 > V4 V4 > V3 > V2 > V1 V1 = V4 > V2 = V3 V2 = V3 > V1 = V4 V1 = V2 = V3 = V4 Cannot be determined 1 2 3 4 5

4 What was the reason that you ranked them that way?
The more resistors, the more voltage the battery supplies The more resistors the less voltage a battery supplies The voltage is used by the first light bulb, then the next … The bulbs on the end use up the voltage first Ideal batteries always provide the same voltage Some other reason 1 2 3 4 5

5 How confident are you about your answer?
I know I’m right I’m pretty sure Neutral I’m mostly guessing I’m completely guessing 1 2 3 4 5
