The older type are a textbook example of series. if one goes out- the entire chain is down- which could prevent fires.
This is the case in a series circuit. (like the small Christmas lights.)
Yes
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.
My dad created a parallel circuit when he plugged in the Christmas lights.

Christmas tree lights, this parallel circuit prevents one bulb failure from turning off the whole string of lights.
It depends on what type of Christmas lights. If they are the (now) standard 50 , 100, 150, mini-lights, they use a 3A fuse and you COULD use a MAXIMUM of about 750 lights if they are strung together from one string (end to end plugs) before blowing the fuse built into the plug of the first light set. If you plug them into separate outlets (or into an outlet-strip), then you could light about 3750 lights on a (otherwidse unused) 15 A household circuit. With the new LED type Christmas lights, it might be even more.
some Christmas tree lights. The circuit through the train. The circuit created when you touch your lips to the train track. p.s. Don't attempt the last one. zzzzzzzzzzT. :<O
If you remove one light from a chain of lights, and the other lights turn off, then it is a 'series' circuit.
Like the old Christmas tree lights, no; lights connected in series will not stay lit if one (or more) are either burned out or disconnected from the circuit. Lights in series are connected "head-to-tail". Take one out, and the circuit is incomplete and will not work.
You might be overloading the circuit. What else is drawing power on that circuit or phase? Are your lights really OK or is there a short somewhere?.
You can find videos of Christmas lights online at the YouTube website. Once on the page, type "Christmas lights" into the search field at the top of the page to bring up the videos.
