Hi

Christmas lights wired in series

240 volt mains ac - 30 lights

what voltage does each bulb have to be?

any words of wisdom?

I'd say 8 volts if put in series. Math: 240 / 30 = 8 Volts

Yes--simple arithmetic: 240/30. I leave the answer as an exercise for
the reader.

I hope that in a few years it [Wikipedia] will be so bloated that it
will simply disintegrate, because I can't stand the thought that this
thing might someday actually be used as a serious reference source.
Because in its current form, it's not to be taken seriously at all.

Are they really in series? That is, when one goes out do they all go
out? Some light strings are series/parallel.

Most 240V sets (UK anyway) are all in series, but each bulb is designed
to self-short if the filament fails - so the rest of the set remain
alight, though sharing now a higher voltage per bulb. Eventually, after
more bulb failures (due to overrun) the fuse bulb will blow and tommy
will get upset, bawl out tears, and santa will head seriously for the
drinks cupboard again.

What's 'Your name' worrying about Christmas for? It's more than six
months away!

Um, cocktail hour here in the states. Good idea.

Most everywhere else are too, though often the larger sets are segmented
with several smaller series sections.

I have one set of UK miniature lights which is very unusual from my
perspective as it has sections of 10 2.4v bulbs in series and runs from
a 24V transformer, that's something I've never seen on this side of the
pond.

Can you give me a little hint?

I'd give you a hint, but I'm getting a little old, and don't
understand this new math, so....

I'm pretty sure that these youngsters today got one part
wrong. They keep saying pie are square, and that's just
not right! Even us old guys know that pie are round,
it's cake that square!

Take care.
