Observation / Conclusion #2

I noticed that the series circuit didnt light up as much as the parallel circuit did, and my hypothesis was correct when one of the bulbs is removed then all the lights will not turn on

Answer

The parallel circuit is the best because if one of the bulbs is removed or bursts the others will still stay on and the parallel circuit is brighter
