Ionized Air Resistance: Research & Questions

AI Thread Summary
Ionized air's electrical resistance varies based on factors like pressure and applied voltage. A tube filled with air at normal pressure ionized by X-rays is likely to exhibit low resistance, potentially comparable to that of metals when highly ionized. Despite initial searches yielding limited results, resources are available that discuss air ions and their properties. The discussion emphasizes the need for further exploration of ionized air's resistivity. Understanding these properties is crucial for applications in fields like plasma physics and electrical engineering.

i am doing a research about ionized air ,and i have little question
how much electrical resistance ionized air have?

Hi moh.gamal. I see you are new here, so http://imageshack.com/a/img515/4884/welcomesign.gif

Resistance probably depends on pressure, and maybe also on the applied voltage. But I'm sure that google will be able to find you all the information you seek. See how you go.

Really thanks for ur reply :smile:, i already searched google ,, i found nothing about that.
A tube full of air at normal pressure ionized by x rays , will the resistance be high or low , what is the approximate resistance ?

Nothing? Maybe start here: http://www.trifield.com/content/about-air-ions/

A highly ionized gas can have a resistivity similar to metal.
 
okay i will take a look :)

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
