Suppose instead that the absolute value of the potential difference across battery A were reduced, but battery B were unchanged (the same as it was in class).
Consider the circuit shown above, which is a variant of the circuit from class. All bulbs are identical, and all batteries are ideal and identical. (Note that the orientation of battery D has changed.)
Use your diagrams to rank the voltages \(V_1\text{,}\)\(V_2\text{,}\)\(V_C\text{,}\) and \(V_D\) from greatest to least. Explain how you determined your answer.
Suppose that bulb 1 were removed, leaving a gap in the circuit. Would this cause bulb 2 to get brighter, less bright, or to stay the same brightness? Explain.
Suppose that battery C were removed, leaving a gap in the circuit. Would this cause bulbs 1 and 2 to get brighter, less bright, or to stay the same brightness? Explain.
The switch shown has been set to the left in the circuit above for a long time (the two batteries are identical). You then flip the switch to the right. Immediately after you flip the switch, what is the current through the circuit?
