Richard,
In simple terms Kirchhoff's loop law says that if we correctly add all of the potential changes around a closed loop we do not end up with a different potential than we had initially. (It does not say just how to handle the computation.) As you may know, there are some non-conservative systems in which this behavior is not true. Traversing around a loop exhibits a spiral behavior. The measured quantity continues to increase (or decrease) with every pass around the loop. Kirchhoff's loop law says this sort of spiral does not happen in an electrical circuit. Computation is "intractable" for distributed RF networks, but the principle is still valid. 73, Gene W4SZ Richard Clark wrote: On Mon, 25 Oct 2004 16:46:50 GMT, Gene Fuller wrote: I am not sure why you think there is a violation of Kirchhoff. Hi Gene, Kirchhoff does not allow for circuits of dimensions that are appreciable size with respect to wavelength. Simple reason is that you should then shrink down the unspecified lead length (for voltage law) into the stray, equivalent and dimensionless components. This is outrageously flaunted in this group, and then couched as examples of modeling failure (when it is in fact modeler - the human component - failure). This is the "intractability" you speak of - the neglect of the proper rendering of the network in dimensionless terms. 73's Richard Clark, KB7QHC |
