Testable Question:
How does the type of circuit affect the strand of Christmas lights with a burned out bulb?

IV-type of circuit DV-strands of lights with burned out
Hypothesis 1:
If the Christmas lights are arranged in a parallel circuit, then when one bulb bursts the other bulbs will light up.

I noticed that all the lights lit up.

I noticed that when you take out a bulb thru lights still lit up.
Hypothesis 2:
If the Christmas lights are arranged in a series circuit, then when one bulb bursts the other bulbs will not light up.

I noticed that all the bulbs lit up.

I noticed that when one bulb burst, none of the lights lit up.

Conclusion:
In conclusion, a parallel circuit would be better to use for Christmas lights because if one light bulb bursts the electricity can take another path to reach the other bulbs.
