## What would happen if one of the lights were removed from a Parallel Circuit?

IV:Parallel Circuit DV: the light

Hypothesis: If the Christmas lights are arranged in a parallel circuit then when 1 bulb is removed the other bulbs stop working.

## Observations

I noticed that even when I removed a light bulb the other bulb still continued to produce light.

## Observation and Hypothesis

Series Circuit

If the Christmas lights are arranged in a series circuit then when I remove a light bulb the light bulb will not produce light.

I noticed when I removed a light bulb the other light bulb also stopped producing light.

## Observation

My observation was I would use parallel ciruit.

## Which circuit would I use?

I would use the parallel circuit instead of a series circuit. The series circuit if a light bulb stopped working ,came unscrewed ,broke , or fell out and the other ones would stop working too. Unlike the parallel circuit would work even if a light bulb fell out , stopped working ,came unscrewed ,or broke. That's what I would choose for my Christmas lights.
