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

Independent Variable: type of circuit.

Dependent Variable: Christmas lights

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 when all the bulbs were connected they all lit up brightly.

I noticed that when I removed one bulb the others stayed lit up. Taking the bulb off did not change the flow of electricity to the other bulbs.

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 when all the bulbs were connected they lit up dimly.

When I removed one bulb the others also turned off. The electricity stopped because there was a split in the wire getting to the other bulbs.

A parallel circuit is the best series to use for the Christmas lights because they produce brighter lights and if a bulb was to burn out the others would still work. If you use a series circuit it is dimmer. When a bulb burns out the electricity can not get to the other bulbs so the other bulbs will not light up. This is unlike a parallel circuit which work a lot Moe conveniently.
