Question

Which are disadvantages of series circuits? Check all that apply.

They are easy to design and build.
They are complicated to design and build.
A break in one wire causes all current to stop.
Current can flow through other branches if there is a break in one branch.
If one bulb goes out, the others stay lit.
If one bulb goes out, the others go out.

Answer 1

Check:
- A break in one wire causes all current to stop. (Yes — series has a single path, so an open anywhere stops the whole circuit.)
- If one bulb goes out, the others go out. (Yes — all components share the same current, so a failed component opens the circuit.)

Not disadvantages / incorrect for series:
- They are easy to design and build. (True but this is an advantage.)
- They are complicated to design and build. (False.)
- Current can flow through other branches if there is a break in one branch. (False — that describes parallel circuits.)
