". In electronic circuit theory, a "ground" is usually idealized as an infinite source or sink for charge, which can absorb an unlimited amount of current without changing its potential. Where a real ground connection has a significant resistance, the approximation of zero potential is no longer valid. Stray voltages or earth potential rise effects will occur, which may create noise in signals or if large enough will produce an electric shock hazard. 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 such as ships, aircraft, and spacecraft 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) There is wrote that all of your transmitter have "a "ground" connection without any actual connection to the Earth." No, that is not what it says or means. Each transmitter needs " an infinite source or sink for charge". No, they do not. The above you know. You are the only one on the planet saying this. But some of you do not know that where the voltage is there is the field electron emission. So the sink is necessary. This is uttter nonsense. It must not be infinite. "a large conductor" absorb the electrons from the air. So its size must be adequate to the emission. This is more utter nonsense. Nice Fun. You are a babbling idiot. |
