Testable Question: How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
IV: Strand of lights
DV: Burned out bulb
Hypothesis: If the Christmas lights are arranged in a parallel circuit then when 1 bulb bursts the other bulbs light up.
Observations
I noticed that when I turned it on that the balls of energy moved through the lights fast, but where the busted light bulb is the energy stopped going through. The lights shined very bright.
Testable Question: How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
IV: Type of circuit
DV: strand of wire
Hypothesis: If the Christmas lights are arranged in a series circuit then when one bulb bursts then the other bulbs don't light up.
Observations
I noticed that the light bulbs didn't shine very bright . Also the little balls of energy moved very slow. When I removed one light bulb the energy stopped moving and none of the bulbs lit up.
Observation
I noticed that when I removed a light bulb none of the other light bulbs lit up.
Conclusion
In conclusion, a parallel circuit is the best series to use for Christmas lights because with one bulb removed the rest would still work, unlike the series circuit.
