Pretty much anything with a resistive element you close a switch to actuate.
Any switch in your house that controls a single bulb is a series circuit. The switch and bulb are in series.
If you have a dimmer switch, the dimmer is in series with the bulb - kinda like a variable resistor - and reduces the voltage/current/brightness of the bulb.
If a switch controls multiple bulbs, they would be in parallel.Possibly the most noticeable series circuit at home are Christmas lights on a Christmas tree. Admittedly it is not a daily life example but more like one in 365 days. I mention Christmas lights as a good example because many people wrestle each year with taking the lights out from last year, put them on the tree and discover that a quarter of the lights don't work. This is generally down to one defective bulb that has severed the series connection that connected a group of bulbs. It is a great example of how other elements in an electrical series circuit are dependent on each other in order to continue functioning and is probably the most easily explained example of an every day series circuit. The fact that all the lights don't fail in this instance is generally due to a typical set of Christmas lights made up of 4 or more series circuits.
