How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
The independent variable is the kind of circuit ( parallel or series). The dependent variable is the number of bulbs that light up.
If the Christmas lights are arranged in a parallel circuit then when 1 bulb bursts (is removed) the other bulbs will light up.
I noticed the blue balls in the wire were going fast and the bulb was really bright.
I noticed that the blue balls were going slower witch made the bulb to be dimmer.
If the Christmas lights are arranged in a series circuit then when 1 bulb bursts (is removed) the other bulbs will not light up.
I noticed that even when u remove one bulb that the other two bulbs are on and bright.
I noticed that when you remove a bulb in a series circuit that none of the bulbs light up.
A parallel circuit is the best series to use for Christmas lights because when you remove a bulb it will still light up. In a series circuit when you remove a bulb none of the bulbs will still light up. Yes they both light up when none of the bulbs remove but if one bulb burst they cant light up but parallel circuit can. Also parallel circuit are way brighter than the series circuit and everyone likes bright bulbs on Christmas. In conclusion, a parallel circuit is the best way to go for Christmas lights.
