One is an essentially infinite sink, and the other ignores that property entirely. So you are arguing with yourself here. The both paragraph are wrote by the same Author. Irrelevant. You are incapable of understanding that the word "ground" can refer to several different things. "The use of the term ground (or earth) is so common in electrical and electronics applications that circuits in portable electronic devices such as cell phones and media players as well as circuits in vehicles may be spoken of as having a "ground" connection without any actual connection to the Earth. This is usually a large conductor attached to one side of the power supply (such as the "ground plane" on a printed circuit board) which serves as the common return path for current from many different components in the circuit." From: http://en.wikipedia.org/wiki/Ground_(electricity) The "large conductor, "ground plane" or "radials" are in the air or in the space. The air or the space are the "infinite source or sink for charge". Nope, they are not. You are incapable of understanding that the word "ground" can refer to several different things. I assume that you know that a conductor gain/loss the charge in the air/space. But the conductor must be large enough. In your "dipole" one radial is enugh but in a big station must be much more. Babbling gibberish The same was wrote by Marconi. It doesn't matter a lot what Marconi wrote as a lot of the things he wrote were later discoved to be wrong or only apply in limited situations. -- Jim Pennino |
