How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
Independent Variables: type of circuit and strand of lights
Dependent Variable: Christmas lights.
If the Christmas lights are arranged in a parallel circuit, then when 1 bulb bursts the other bulbs will light up.
I noticed that the brightness of the bulbs was very bright.
I noticed that the brightness of the bulbs went down when one was removed, but it was still very bright.
If the Christmas lights are arranged into a series circuit, then when 1 bulb bursts the other bulbs will not light up.
I noticed that the bulbs were not as bright as the parallel circuit.
I noticed that the bulbs did not light up at all unlike the parallel circuit.
I conclude that a parallel circuit is the best circuit series to use for a strand of Christmas lights because they are much brighter and all of them do not burn out when one breaks or burns out like a series circuit.
