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

I.V. parallel circuit and series circuit

D.V. light

Hypothesis: 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 that the electrons moved very quickly in the parallel circuit.

I noticed that the electrons moved very quickly in the parallel circuit.

I noticed that when you remove a bulb the other bulbs still light up.

Hypothesis: If the Christmas lights are arranged in a series circuit then when 1 bulb bursts (is removed) the other bulbs will nit light up.

I noticed that the electrons moved very slow.

I noticed the when you remove a bulb in the series circuit the other bulbs will not light up.

A parallel circuit is the best circuit to use for Christmas lights because if one light gee out the other ones still light up and its not noticeable but if it is a series circuit then when 1 bulb bursts then the rest of the lights will go out a well and a lot f people will notice.
