参考答案: If the lights are connected in
parallel, if one bulb burns out, the rest of the string stays lit. That makes it easy to tell which light has
gone out. A parallel string is more
complicated to assemble than a series string, since two wires must be attached
from bulb to bulb.
If the
lights are connected in series, if one bulb burns out, all of the bulbs will go
out. That makes it difficult to tell
which light has gone out. A series
string is simpler to assemble than one in parallel, since only one wire must be
attached from bulb to bulb. A “blinker
bulb” can make the entire string flash on and off by cutting off the current.
