Conclusion

Conclusion- A parallel circuit is the best series to use for Christmas lights because if you take one bulb out the rest will be bright and still work. It is only the bulb that busted that won't work. The bulbs that are still lit are bright like they were before. In a series circuit if one stopped working they all stopped working, but that isn't the case with a parallel circuit they still work even without one bulb not working.
