1. The problem statement, all variables and given/known data Given the circuit diagram (attached below), predict how unscrewing each bulb separately affects the brightness of the other two bulbs? 2. Relevant equations N/A 3. The attempt at a solution I predict that by unscrewing one of the bulbs, the other two will get brighter. This is because there is less resistance in the circuit overall, and more current which is distributed to the other two bulbs, making them brighter. Am I on the right track here? I am only at a basic high school level so this is the best explanation I could think of given my knowledge. Any help is very much appreciated!
