Question

I find an assortment of commercial light bulbs (like those you'd use in a lamp), connect them together in an end-to-end seriescombination, 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.

I find an assortment of commercial light bulbs (like those you'd use in a lamp), connect them together in an current-splittingparallel 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.

Explanation / Answer

1. All be dimmer than usual.

since new resistance is introduced in series, Effective resistance increases   and current decreases, but same current flows across all the bulbs

2.All be brighter than usual.

here due to parallel comboination effcetive resistance decreases aand current increases

remember: same current flows in series combination of resistors and current divides in parallel combination of resistors
