Christmas Light Webquest
Working with parallel and series circuits.
This project was a study on which circuit works better for a Christmas light strand that has gone bulb go out.
How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
The I.V. is the type of circuit used.
The D.V. is which bulbs work after one bulb doesn't.
If Christmas lights are arranged in a parallel circuit then when 1 bulb bursts then the others will still light up and work.

I observed that the more batteries I added, the faster the current went and the brighter the bulbs shined. Also I noticed that the current had two ways to travel instead of just one.
I observed that even when one bulb "burst" the parallel circuit still caused the others to work, which is ideal for your Christmas lights you put on your tree.
If Christmas lights are arranged in a series circuit then when 1 bulb bursts the others will not work.
Series Circuit Screenshot
I noticed that the light isn't as bright with just one battery. Also I observed that there is only one way to get the current through.
I observed that in a series circuit it only has one way to travel, causing all other bulbs to stop working.
I conclude that the parallel circuit will work best for a Christmas light strand
