@apogeum ,
Even hard core physicist will tell you that field theory for electrical conduction is rarely consequential to the outcome, though we both use and experience it day in and day out in the form of transformers, RF, and EMI. Contrary to what our friend @teo_audio states, engineers often use fairly complex model for inductance, electrical fields, etc. even to the point of doing finite element analysis for things like transformers, antennas, sensors, electromechanical semiconductor elements, semiconductors period, etc.
When dealing with things in isolation, ohms law works just fine and is more than accurate enough for audio, and we do use that knowledge of fields, mainly to shield ourselves from the instances where they become an issue with the exception of transformers. All the semiconductors we use benefit heavily from our knowledge of fields and how they apply to electrical conduction and hence once could say that knowledge has greatly led to improved audio.
Unfortunately, a little knowledge is a dangerous thing, so when some grab onto this knowledge without fully understanding said knowledge, they come to erroneous conclusions, mainly from not understanding the magnitude of effects. Lot's of "interesting" things said about cables that a little analysis would show can't be remotely audible.
It is not unlike things with Covid. People latch onto things that match what they believe already, so they see a study that says 60% of infected people are vaccinated and they jump to or are easily led to the conclusion that vaccines don't work or worse cause more infections. They don't dive deep into the data that shows that 80% of the people are vaccinated, hence relative infection rates are 60/80 for vaccinated versus 40/20 for non vaccinated (using representative but not real numbers). The further don't delve into age related stats that skew that data even more towards vaccine effectiveness.
