Question

Ron is dreading setting up the Christmas tree because the lights are always a hassle. There is always at least one strand of lights that has a bulb out that prevents the string from lighting because the broken bulb breaks the circuit. He must test all the bulbs to determine which bulb is damaged and replace it before the light strand will work properly. If his lights were wired as a ________ circuit instead of a ________ circuit he could avoid this headache.

Answer 1

D

Step-by-step explanation:

The correct answer is D. parallel, series.

If Ron's lights were wired as a parallel circuit instead of a series circuit, he could avoid the hassle of dealing with a whole strand of lights going out due to a single broken bulb. In a parallel circuit, each bulb has its own separate pathway for current flow. This means that if one bulb burns out or becomes damaged, the other bulbs will still remain lit because the circuit is not interrupted. In contrast, in a series circuit, all the bulbs are connected in a single pathway, so if one bulb fails, it breaks the circuit and causes all the other bulbs in the series to go out.
