Christmas Lights Webquest
How does the type of circuit affect the strand of Christmas lights with a burned out bulb?
Independent Variables: Type of circuit, and number of light bulbs removed.
Dependent Variable: Number of lights that lit 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 when you connected all of the wires to the bulbs and battery it brightly lit up.
I noticed when you remove a light bulb nothing happened.
If the Christmas lights are arranged in a series circuit then when 1 bulb is removed the other bulbs will not light up.
I noticed that the light bulbs were as bright as they were in the parallel circuit.
I noticed when the one light bulb was removed there was no more light being produced.
A parallel circuit is the best circuit to use for Christmas lights because even if one light bulb goes out all the rest still work.
