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.

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.
