Series and Parallel Circuit Series and parallel circuits are two fundamental configurations in electrical circuits, each with distinct characteristics that affect how electricity flows through them.

And, unlike a series circuit, the lamps stay bright if you add more lamps in parallel. Parallel circuits are useful if you want components to continue to work, even if one component has failed.

In a parallel circuit, if a lamp breaks or a component is disconnected from one parallel wire, the components on different branches keep working. Unlike a series circuit, the lamps stay bright if ...

Let's pretend like we have a different circuit. In this one, I have 5 lightbulbs in series connected to a battery. Oh, and all the lightbulbs work.
