Talk:Characteristic impedance of vacuum

This information is all in the CI page. I don't see any grounds for a separate page. Also the actual value given is different which is confusing.


 * If something is different and not incorrect, then obviously all information is not there. That should merit it alone from blanking unless the information is tranfered over.


 * While impedance is not really my thing, vacuum constants often if not always should merit their own instance, since often it can represent quite a different thing. As an example there is speed of light in vacuum which could be interpreted as a real phenomena, while values different from that (speed of light in medium) could be regarded as a fictous thing.

 * Well, I see that impedance is not your thing. The impedance of a transmission line is the ratio of volts in the line (the ones you measure with a voltmeter) and amperes in the line (the ones you measure with an ammeter). The impedance of free space is an universal constant and has nothing to do with volts, amperes or transmission lines. I created a stub for vacuum impedance, and I am linking this page to this stub. Please consult an electromagnetism book before redirect unrelated pages. LPFR 10:16, 15 September 2006 (UTC)
