Light Bulbs in Series and in Parallel. Two light bulbs have resistances of 500 ? and 1000 ?. The two light bulbs are connected in series across a 110 V line. (a) Find the current through the 500 ? bulb. A Find the current through the 1000 ? bulb. A (b) Find the power dissipated in the 500 ? bulb. W Find the power dissipated in the 1000 ? bulb. W Find the total power dissipated in both bulbs. W The two light bulbs are now connected in parallel across the 110 V line. (c) Find the current through the 500 ? bulb. A Find the current through the 1000 ? bulb. A (d) Find the power dissipated in the 500 ? bulb. W Find the power dissipated in the 1000 ? bulb. W Find the total power dissipated in both bulbs. W (e) In each situation, which of the two bulbs glows the brightest? The 500 bulb is brighter when the resistors are in series, and the 1000 bulb is brighter when they are in parallel. The 1000 bulb is brighter when the resistors are in series, and the 500 bulb is brighter when they are in parallel. The 1000 bulb is brighter both when the resistors are in series and when they are in parallel. The 500 bulb is brighter both when the resistors are in series and when they are in parallel. In which situation is there a greater total light output from both bulbs combined? The greatest total light output is when the bulbs are in series. The total light output is the same in both cases. The greatest total light output is when the bulbs are in parallel.
