Question

there's a collection of commerical lights bulbs (like in lamps), connect them together in an end-to-end series combination, and put the two ends across the wall socket's voltage difference. In this configuration, the bulbs will:

All be dimmer than usual.

All be brighter than usual.

All have the same brightness, which means some are dimmer than usual and others are brighter.

Have zero current flowing through them, because light bulbs aren't designed to be connected in series.

there's a collection of commercial lights bulbs (like in lamps), connect them together in an current-splitting parallel combination, and put the two ends across the wall socket's voltage difference. In this configuration, the bulbs will:

All be dimmer than usual.

All be brighter than usual.

All be as bright as usual.

Have zero current flowing through them, because light bulbs aren't designed to be connected in parallel.

All be dimmer than usual.

All be brighter than usual.

All have the same brightness, which means some are dimmer than usual and others are brighter.

Have zero current flowing through them, because light bulbs aren't designed to be connected in series.

Explanation / Answer

there's a collection of commerical lights bulbs (like in lamps), connect them together in an end-to-end series combination, and put the two ends across the wall socket's voltage difference. In this configuration, the bulbs will:

All be dimmer than usual.--- this is because effective resistance of series combination is larger than any individual resistance and this resistance opposes the flow of current, high is the resistance, high is the opposition and less is the current

All be brighter than usual.

All have the same brightness, which means some are dimmer than usual and others are brighter.

Have zero current flowing through them, because light bulbs aren't designed to be connected in series.

there's a collection of commercial lights bulbs (like in lamps), connect them together in an current-splitting parallel combination, and put the two ends across the wall socket's voltage difference. In this configuration, the bulbs will:

All be dimmer than usual.

All be brighter than usual.---- this is because efffective resistance of parallel combination is smaller than their individual resistances, less opposition , more current

All be as bright as usual.

Have zero current flowing through them, because light bulbs aren't designed to be connected in parall

All be brighter than usual.

All have the same brightness, which means some are dimmer than usual and others are brighter.
