Please could someone give me a couple of examples of uses of series circuits and the same for parallel circuits. Thanks ever so.

Please flesh out your question.

Are you talking AC or DC circuits? Electrical circuits or electronic circuits?

Are you looking for power distribution sources or load distribution?

Christmas tree light strings that go out when you pull out one bulb are series circuits. The outlets in your home are parellel wired.

In words, series would be 2 or more loads in line(Christmas lights?) if 1 goes out, other goes out. 2 equal loads in series would draw half current of 1 load by itself.
Parallel is like if you had 2 bulb sockets and connect the blacks of each socket, and the whites of each socket to the line, load would be double of 1 socket(equal bulbs).
In speakers, you can have positive of 1 speaker connect to the negative of second speaker, then the 2 8 ohm speakers would measure 16 ohms in Impeadance(resistance).
2 8 ohm speakers in parallel would equal 4 ohms.
You can take 4 8 ohm speakers and do a
Series parallel,Series the 2 pair, then parallel the remaining 4 wires.
This way your amp will see 8 ohms.
Some people will hook several speakers to the output in parallel, it will keep loading down, 4 in parallel would show 2 ohms at amp and likely destroy.
