Why neon-filled glass pipes in neon signs are always connected electrically in series, and never in parallel?

Answer 1

It's not just that the parallel tubes won't light evenly; some may not light at all. The ionization potential increases with length, and once ionized, a tube will behave like a nonlinear resistor, with self-heating tending to decrease resistance and increase current. Neon transformers are designed with high internal resistance that tends to limit the available current as the voltage across the load decreases. If the next-shortest to shortest length ratio is high enough, this combination of electrical characteristics allows the shortest tube to "hog" the available current, by limiting the voltage to a value less than the next-shortest tube's (and any longer tubes') ionization voltage.

Answer 2

Jesus did now not tutor scripture on my own. and lots of what hes stated and did is a ingredient of our -- Catholic -- unwritten background. the hot testomony isn't a transcript of each 2nd of Jesus's life or ministry. this is the tale of the fondation and early formation of the catholic churhc. The Gosples are the speivifc trainng that Jesus first bishops recived at his hand -- He hadn selections them trains them appoints a frontrunner, ordains him is crucified rises type the ded and ordains the relax. Int he interim instuting the scaraments. The gosples are extra and description highlighten the main iimportant spects of Jesus's venture which turn into to got here across His kingdom on the earth, which consists of teh instution of the sacraments. UNderstood in this contxt sripture makes suitable experience. outdoors of this context it is not clever and all varieties of errenous notions and missunderstandings are produced. This si why -- the context -- this is particularly hassle-free for a catholic to communicate a protestant particualrly the sola -scrupture or "fundies" becasue all of us be attentive to the trutht and the authentic context so we've the certainty with us, and might easliy straineout fake recommendations brough approximately with the help of each indiviudal inperpting the owrds for themselves. So no now not something ought to be extra fro the certainty Jesu gave scripture this is maximum appropriate and definitely exalted palce yet he did now not convey the concept of sola sripture or he could have wrote himslef, he could have spent his time writng and not fouodning he church. Sola scripture is a style of idolatry which negates the actul jesus, aND UINDEED a private REALTIONSTHP WITH HIM this is purely attainable for the duration of the sacrametns.. It elavtes the bible to the sataus of God. certainly many call it the word of god while in certainty weknow that jesus is the word of god and the bible incorporates the words of god.

Answer 3

Brightness depends on current. In a series setup, all elements have the same current, so the same brightness. If you hooked them up in parallel, shorter lengths might have lower resistance and higher current, making them light up unevenly.

Answer 4

If you connected N tubes in series, the voltage drop across any one of them would drop by factor N. But you need a certain minimum electric field (proportional to the voltage drop) for the tubes to work. So you can't afford to drop the voltage across a tube.
