Question

which is an advantage to using a series circu
series circuits use less wire.
if one bulb goes out the others stay lit.
series circuits are a complex circuit.

Explanation:

In a series circuit, components are connected end - to - end, so there is only one path for current to flow. This simplicity means that less wire is needed compared to more complex circuits like parallel circuits where multiple paths are created. If one bulb in a series circuit goes out (opens the circuit), the current stops flowing and all bulbs go out. Series circuits are actually relatively simple in design compared to some other types of circuits (like combination circuits).

Answer:

Series circuits use less wire.
