This thread is intended to address a question in the now-closed Q&A thread Does this qualify as an electrical current flow?
The question comes from neilzero, in response to a post by korjik:Originally Posted by korjikI replied to this question as follows:Originally Posted by neilzeroSo here are the questions this thread seeks answers to:Originally Posted by Nereid
1) What is the pressure inside a 1/25 watt neon light?
2) How much energy does it take to turn the neutral gas in such a light into a plasma (in the light's normal working state)?
3) How long after the energy source is removed does the plasma turn back into a gas, near ambient temperature?
In all cases, an order of magnitude (OOM) answer is what I'm after.
For 1) and 2), standard SI units please.
I'd really like it if amateurs and high school or undergrad university students tried to answer these ... I'd be astonished if any professional physicist/space scientist/astrophysicist or grad student couldn't!
Note that one way to answer 2) avoids a need to know a great deal about neon.
And if anyone finds (or knows of) a site with both a nice piccie and specs for a neon light of the kind neilzero describes, I'm sure that would help readers who have may never have heard of, let alone seen, such a thing ...
