That's not how parallel circuits work. The voltage is independent of how many devices are connected. That's how your wall plugs always provide 110V.

Edit: Sorry, I misread, I thought this subthread was about parallel circuits.

It's not a parallel circuit. It's a series circuit. If you have 100 bulbs in series, each is getting 1.1V across it.

If half of them burn out (and, as the article explains, become a short-circuit), then you have 50 bulbs, and each is getting 2.2V across it.
