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.

A break in one wire causes all current to stop.
 If one bulb goes out, the others go out.

   A series circuit is one in which the current flows from device to device in series. Think of a long change, the links of the chain are in series with each other. So let's take a look at the options and see what makes sense.

    They are easy to design and build.
 * This statement is quite true as regards a series circuit. But it also is an advantage, and since we're looking for disadvantages, it's a bad choice.

They are complicated to design and build.
 * Definitely a disadvantage. But it doesn't apply to a series circuit. So another bad choice.

   A break in one wire causes all current to stop.
 * Quite true. A series circuit either works, or it doesn't. And a failure in any component will cause the circuit to not work. So this is a good choice.

Current can flow through other branches if there is a break in one branch.
 * This is a description of a parallel circuit and doesn't apply to a series circuit, so it's a bad choice.

   If one bulb goes out, the others stay lit.
 * Another item for parallel circuits. So another bad choice.

   If one bulb goes out, the others go out.
 * Yes, this is true. Failure of any part of a series circuit will cause the entire circuit to fail. So this is a correct choice.
