how does a parallel circuit affect the light seen?

DV: light seen


if the Christmas lights are arranged in a parallel circuit then when one bulb burst or is removed the other bulbs shows or does not show light.

I noticed the when you connect the wires the blue dots move rapidly.

When you remove the bulb the other two lights still light up.


if the Christmas lights are arranged in a series circuit then when 1 bulb burst or is removed the other bulbs light up.

i noticed that the blue dots move very slowly and the light is very dim.

A parallel circuit is the best serious to use for Christmas lights because if one burst then the rest will still be lit. in a series circuit if in burst then all lights will turn off. this is why it is better to use a parallel circuit for a Christmas tree. it will save much more money. also much less work.
