Question
For each of the questions 6-8 below, a wire is connected from the battery terminal at point 1 to point 4 as shown in the figure below. What happens to the brightness of each of the three bulbs? Explain
B goes out, A stays the same and C gets brighter than before to be about as bright as A. This is because the wire through 1 and 4 disconnects the bulb B from the battery and since B is disconnected the resistance of the circuit parallel to A, through C alone, is now the same as A.
A stays the same but B and C get brighter because now there are two ways for the current to go through B and C: one along 1 to 3 and the other along 1 to 4.
C gets brighter, A and B stay the same because now there are two ways for the current to go through C: one along 1 to 4 and the other along B to 4.
B gets brighter, A and C stay the same because now there are two ways for the current to go through B: one along 1 to 3 and the other along 1 to 4.
All the bulbs stay the same because the wire has no resistance and total resistance in the circuit is not changed.
