(hic) Not sloshing up against the source - forced back through the source and out the other source terminal (just like a battery). Do you understand what happens when you reverse the polarity of a battery in a DC circuit? Current flows in the opposite direction. AC is somewhat similar to reversing the DC battery polarity. In any one AC supply wire, AC current flows away from the load toward the source 1/2 of the time. Electrons flow back and forth through the source. Electrons flow back and forth through the load. The electrons near the source may never make it to the RF load and vice versa. The driving EMF changes directions every 1/2 cycle. It appears that the DC model adapted for AC has seduced a lot of people into ignoring the most basic characteristics of an AC signal which is somewhat like reversing the polarity on a DC battery. -- 73, Cecil, W5DXP |

Cecil, OM. The point you so hard-headedly and steadfastly refuse to acknowledge is that YOU are the one trying to employ a "DC model" when describing alternating current. AC doesn't go into one end of something and then come out the other end of that thing. If you would simply acknowledge that fact then maybe we wouldn't have to endure any more of your 2nd Grade electricity tutorials. Okay? 73 de AC6XG |

AC doesn't go into one end of something and then come out the other end of that thing. If you would simply acknowledge that fact then maybe we wouldn't have to endure any more of your 2nd Grade electricity tutorials. Here's a snapshot of the current maximum points, including direction of current flow, in a 2 WL matched transmission line. The next snapshot is the same thing 1/2 cycle later. Note: Current is going into the bottom of the source and coming out of the top. Same for the load. *----------------------* | | Source Load | | *----------------------* *----------------------* | | Source Load | | *----------------------* 1/2 cycle later: Current is flowing out of the bottom and into the top of the source. Same for the load. The transmission line is 2 wavelengths long. That means that instantaneous current in the transmission line is simultaneously flowing toward the load and toward the source at different points up and down the line. AC is akin to reversing the polarity of a battery. What happens to the direction of current flow through the load when the polarity of a battery is reversed? Don't you realize that if current is flowing out of the '+' terminal of a battery, that same current is flowing into the '-' terminal? -- 73, Cecil, W5DXP |

and then come out the other end of that thing. If you would simply acknowledge that fact then maybe we wouldn't have to endure any more of your 2nd Grade electricity tutorials. Okay? 73 de AC6XG So when I plug my toaster into the AC outlet the current doesn't go into one end? The same with transmitter and antenna? Live and learn (garbage)? Yuri |
