When four identical light bulbs are connected in parallel and this combination is connected to an ideal battery, the bulbs each glow with a certain brightness until the battery runs down after six hours. [Recall that an ideal battery is one with no internal resistance.] If two of the light bulbs are removed so that there are just two light bulbs in parallel and then this combination is connected to a new (but otherwise identical) battery, Question 6 options: the...
