Let’s say that you are installing six lights in a building. A parallel circuit starts with a hot wire and a neutral wire which feeds the first light. The remaining five lights are connected white to white (neutral) and black to black (hot) all the way to and including the last light. Unlike the series circuit, you can remove a bulb in any of the lights and it will not cause the other lights to go out. A great example is a hallway in your house where two or more lights come on with the same switch. When one burns out, the other remains lit.
Let’s take a string of Christmas lights for example. When you take out one bulb and they all go out, that is a series circuit. If you take a bulb out, you’re opening up the circuit and that means that current cannot flow.
Parallel Christmas lights are better than series Christmas lights. In a parallel circuit when one bulb goes out the rest remain on because the current keeps on flowing.
