The Kirchhoff law of current relates to the flow into and out of "a closed surface" or a point (where any number of components' common leads come together) and not to the components themselves (as they have been incorrectly injected as argument). The corruption is found in that the current law has been expressed in the language of Kirchhoff's voltage law by nearly EVERY correspondent. EZNEC treats loads as lumps, lumps are the metaphor for the "closed surface" or a point. EZNEC conforms to Kirchhoff's current law, but not the physical reality simply because in nature a load cannot exhibit its characteristic within a point (there are no infinitesimal capacitors or inductors). Hence a protocol was offered to decimate the inductor and spread its characteristic across the apparent physical space to achieve the same, virtual response of a true inductor immersed in reality. The result of the protocol exhibits roughly the same characteristics offered by ON4UN's drawings (which are also approximations themselves). 73's Richard Clark, KB7QHC |
