Coils are transmission lines

I ignored the harmonic examples. Who ever said that a coil would be a lumped inductor when it is operated above its self resonant frequency? Oh, I forgot to ask you a technical question, Gene. Given that at 11.78 MHz, the current at the bottom of the coil is 0.17 amps and the current at the top is 2.0 amps, how do you explain those values if the current is flowing up through the coil? The details are at the bottom of the following web page. -- 73, Cecil http://www.qsl.net/w5dxp/current.htm |

I don't recall anyone ever questioning such matters. Only in your imagination does anyone deny the existence of distributed, non-lumped components. If there really is such a person, it might be better to address your query to him or to her. 73, Gene W4SZ |

The details are at the bottom of the following web page. I don't recall anyone ever questioning such matters. You seem to be trying to have it both ways. 0.17 amps is not equal to 2.0 amps. 0 degrees is not equal to 180 degrees. How are those values possible in a lumped inductor? -- 73, Cecil http://www.qsl.net/w5dxp |
