2. For parallel circuits, you saw that the potential difference across each resistor was the same as the potential difference of the battery. Use your rule for potential difference in series circuits to explain why this would happen. Hint: Imagine following an electron as it leaves the battery, travels one of the paths through the circuit, and returns to the batter What is true about the changes in potential difference for the electron in each type of circuit? What would happen to the potential difference if you only had one resistor in series?

7. You want to reduce your carbon footprint in the next Yuletide season, so you plan to re-use last year's Christmas lights to your Christmas tree. You notice that one of the lightbulbs stops working but the other remaining bulbs are still in good condition. What is your hypothesis regarding how these lightbulbs are connected? Group of answer choices The lights are connected in a series circuit. The lights are connected in a parallel circuit. It would be impossible to determine the type of connection for the lights without dismantling the wiring. The lights are connected in a combination of series and parallel circuits.
