An unknown number (greater than two) of light bulbs are connected in series, and then the combination is connected across the terminals of a battery. Each connecting wire has zero resistance. The resistances of the light bulbs are also unknown, and they are not necessarily all the same. What happens to the brightnesses of the remaining light bulbs when one of the light bulbs is chosen at random, removed from the circuit, and not replaced with anything?
Multiple Choice
They increase.
They decrease.
They stay the same.
Some increase and others decrease depending on the resistances of the light bulbs.
Some increase and others decrease depending on the number of light bulbs remaining.
