Hi all,
Excuse me for the generic nature of this question but I'm at the
very beggining of something and thus I need some answers which someone
could easily declare nonsense... Anyway, here I go:
Are there any materials (liquid or gas) that glow when they are run
through by electricity? I think I've heard that there is such a gas,
but I would prefer something in liquid form(while at room
temperature). If there are any, what electrical current do they need
to glow? |

gases include neon, argon, etc.
If you include the use of phosphors, then you can throw in mercury and
others.
Liquids . . . someone else can field that.

"Neon" Signs are all gas, but use high voltages (usually 5000+ V). As for a
solid, Nicrome wire is a common one that is used in toaster filaments.
There are probably others (do electric stoves use something else?), but I
don't know of them. I also don't know of any liquids either. Current wise,
just experiment. "Neon" lights use less than 30mA, and Nicrome wire (I'm
not sure) may take over 500mA, but at a low voltage. |
