The light bulbs in the circuit are identical. When the switch is closed, ANSWER: BRIEFLY EXPLAIN YOUR ANSWER: 1. both go out. 2. the intensity of light bulb A increases. 3. the intensity of light bulb A decreases. 4. the intensity of light bulb B increases. 5. the intensity of light bulb B decreases. 6. some combination of 1-5 occurs. 7. nothing changes.

However, I can provide some general insights. If the light bulbs are in series (one after the other), closing the switch would not change anything because the current would still have to pass through both bulbs. So, the answer would be 7. nothing changes. Show more…

(GRAPH CANNOT COPY) Three identical light bulbs are connected to a source of emf, as shown in the diagram above. What will happen if the middle bulb burns out? (A) The light intensity of the other two bulbs will decrease (but they won’t go out). (B) The light intensity of the other two bulbs will increase. (C) The light intensity of the other two bulbs will remain the same. (D) More current will be drawn from the source of emf.
