Old-fashioned fairy lights used on Christmas trees were connected to each other as part of a series circuit. Explain the difficulty this would cause if one of the bulbs broke and suggest why arranging them in a parallel circuit would be better.

Explanation:

Rhett Allain Fuses in a strand of Christmas lights. If you connect too many strands of lights together then the current will be too large. The fuse will go out to prevent these things from getting too hot. However, sometimes these little fuses just get loose after storing the lights in the off season.

Hope it helps :)

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
