Inductance of transmission lines in vacuum

Click For Summary

Discussion Overview

The discussion revolves around the inductance of transmission lines when placed in a vacuum. Participants explore whether inductance is affected by the medium surrounding the transmission line, specifically in a vacuum context.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions if inductance can exist in a vacuum, expressing uncertainty about the concept.
  • Another participant asserts that transmission lines have inductance and capacitance in any medium, including a vacuum, but does not elaborate on the implications.
  • A later reply emphasizes that inductance does not significantly change due to the surrounding medium, suggesting that it is independent of whether the line is in a vacuum.
  • Some participants discuss the limitations of the forum's messaging system, particularly regarding the inability to display diagrams, which diverges from the main topic of inductance.
  • There is a repeated emphasis on the idea that inductance is present as long as there is a current, regardless of the medium.

Areas of Agreement / Disagreement

Participants generally agree that inductance exists in a vacuum, but there are varying levels of elaboration and understanding regarding the implications of this. Some participants express frustration with the forum's features, which may distract from the technical discussion.

Contextual Notes

There are unresolved questions about the nature of inductance in different media and the implications of these discussions on practical applications. Some participants express dissatisfaction with the forum's capabilities, which may affect the clarity of technical discussions.

hello frnds, I am in jeopardu regarding d thing ,so u gyz uot there pleeze tell me can we have a inductance of a transmission line placed in vaccum?
hope u gyz will pull me outta this soup.

Yoiks. Looks like you got a little trouble with your keyboard there, scout. To answer your question (or what I think your question is) -- Yes, transmission lines have inductance and capacitance in any medium, including a vacuum.

Why do you ask? (and please try to type a little better...?)
 
..and on a related topic, why can't you display diagrams or pictures directly in a message, but you can have letters 30 feet tall? How useful is that?

Because the size of the font does not alter the bandwidth needed to transmit a message while a photograph will. Additionally, allowing photos means you must moderate all photos(lots of work) or you must put up with the occasional naughty picture(not good when young ppl are around or foreign ntls who do not approve of such images frequent a site).

There are probably other reasons but I'd bet dollars-to-donuts the above are big players.

Yes. Inducatnce does not come frrom the air and is not significantly
altered by it.

Not a good enough reason. All other physics forums manage to handle these problems fine.

..yes, inductance doesn't matter whether it is in a vacuum or not, as long as there is a current that will pass inductance is there
