If we assume the coil is an idealized lumped inductance with no stray capacitance at all (not a real inductor) then it would have the same instantaneous current at each end and that current would be zero, since it has zero size. In other words it would fit entirely in the point that holds the node. And such a coil is impossible in the real world so why even mention it? I want to hear about real world one foot long, 100 uH coils. Real inductors with stray capacitance and imperfect magnetic coupling for all parts of its internal current path, would have a phase shift in the current at opposite ends, so they would have current at their ends that was 180 degrees out of phase, if they were centered on the node points. Yes, now please tell that to W8JI and W7EL. They are not listening to me. I am not arguing for the validity of that measurement. Argue about it with someone who is. That's my entire argument at the moment and W7EL is avoiding that argument like a plague. In case you don't realize, there is more than one person out here, responding to you. Please forgive me for not recognizing which of the ten individual junk yard dog "experts" is biting my ankles at any particular time. :-) You remind me of a type of insanity where the sufferer thinks that everything he is experiencing an organized illusion by a single offending intelligence (you against the Matrix) bent on forcing him to think that a lie is the truth, regardless of who or what he deals with. Everyone he meets, every apparently random happenstance, the actions of his dog and the weather, generally, are all a conspiracy to force him to think that black is white, and he isn't going to fall for it. IMHO, hardly anyone here on r.r.a.a is interested in technical facts. Most "experts" think they already know everything, wouldn't recognize a differing concept if it bit them in the arse, and are more dedicated to preserving the pecking order than anything else. 'Course, I am only human and could, therefore, unlike the omniscient experts, be wrong about that. -- 73, Cecil http://www.qsl.net/w5dxp |
