Yes you would use a serial circuit
You would use parallel circuit lights for a Christmas tree because if you used series circuit lights, and one of the bulb blows, the rest of the bulbs will go out.
But with parallel circuit lights, if one bulb blows the rest of the bulbs will remain their brightness.
both
In a series circuit, if any one bulb goes open the rest of the lights will go out. The current flow in a series circuit is common throughout the whole circuit. In a parallel circuit when one bulb goes open the rest remain on due to the configuration of a parallel circuit.
series circuit
My dad created a parallel circuit when he plugged in the Christmas lights.
They are parallel, or at least you HOPE they are parallel.
No, electric lights come in both parallel and series circuit.
Two receptacles on a branch circuit, each in parallel, both in series with the circuit breaker. The blower motor, ignition transformer, and oil solenoid on an oil burner, each in parallel, all in series with the acquastat (water temperature control switch).
Christmas tree lights, this parallel circuit prevents one bulb failure from turning off the whole string of lights.
With series Christmas lights, if one burns out, the whole string stops working. With parallel Christmas lights one light burning out only affects that light. This makes it much easier to replace burned out lights in the case of the parallel lights.
Yes
Parallel circuits are used when there are many electronics on the same circuit, such as Christmas lights, for example. If they were on a series circuit, if one bulb went out all of them would go out. In your home, parallel circuits allow you to turn any electrical device on or off, independently of the others.
In a parallel circuit, there are multiple paths for electricity to flow. So, if one switch is turned off there is still other paths for electricity to flow so the other lights can remain on. However, in a series circuit there is only one path for the electricity to travel. So, if the switch in a series circuit was turned off the electricity would stop flowing causing all the lights to go out.
