Hi,
My name is Ivan. Welcome to my cottage. Feel free to look around. I hope you can help us fix the mosquito device. I really hate the smell of Off.

Your study is so brightly lit!
Why thanks. That's why I'm wearing these stylish sunglasses. It's so brightly lit because I have two lightbulbs arranged in series. This switch turns both of them on or off at the same time. I can't control each of my lightbulbs independently. This is why my study is always so bright.
Do the lightbulbs last long?
The bulbs last quite long. But I find that when one of them blows, both my lightbulbs will not light up.
Have you tried a different configuration?
I've never thought about it. I wonder how a parallel configuration will work...
