Two identical lightbulbs are connected to a battery, either in series or in parallel. (a) When the bulbs are connected in seriesare they brighter than, dimmer than, or the same brightness as when they are connected in parallel? (b) Which of the following is the best explanation for your prediction?I. The bulbs are brighter when connected in series because the same current passes through each of the bulbs, as compared to the parallel case where the current is split between the two bulbs.II. The bulbs are dimmer when connected in series because the voltage across each bulb is less in series than it is when theyare connected in parallel.III. The bulbs have the same brightness in either case because the same bulbs are connected to the same battery
