Christmas Light WebQuest
How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
The independent variable is the burned out bulb and the dependent variable is the circuits used.
If the parallel circuit has a burned out bulb, then the lights will not work.
I noticed that all of the lights lit in the parallel circuit.
When one bulb is removed or burned out the lights still shine.
If the series circuit has a burned out bulb, then the series will fail.
The light in the series circuit is dim, but is still shining.
None of the lights worked when one bulb was removed.
A parallel circuit is best for Christmas lights because when one is removed the series will still work.
