What kind of connection is used for Christmas light?

Answer 1

series and parallel circuit :)

Series Circuits

• Some strands of Christmas lights use a series circuit, also known as a closed circuit. The current goes to each bulb in order, without going in any other direction. All components of the strand of lights work in a path. If one bulb burns out, or one bulb is taken out of the strand, no charge will move through the circuit. The strand will stay off because the series has been interrupted, and the path broken.

Parallel Circuits

• The other type of Christmas light strands uses a parallel circuit. This is a closed electrical circuit where the current is wired in parallel, like rungs on a ladder. The current is divided into at least two different paths. Energy flows only through a common path to complete the circuit. In the case of Christmas lights, this means that there is more than one current going to the bulbs. If one burns out, the others will still lighted because the the current going to each one is separate.
