What? No lumped inductors in reality? :-) What about
the measured 3 nS delay through a 100 uH coil?

Delay through a coil... what is that? Heh, heh...

Nickola Tesla would be rolling over in his grave if he could hear us
discussing a possible dichotomy between lumped and distributed systems.
Nickola "lived" in the intersticies between the wave theoretic and circuit
theoretic fabrics of reality.

It is interesting is it not, that the "only" element of circuit theory that
allows for "action at a distance" [a.k.a. "field effects"] is that of mutual
inductance "M".

Circuit theoretic elements; R, L, C, and M...

Other than "M" circuit/network theoretic concepts are devoid of the wave
theoretic aspects of the celebrated Maxwell/Heaviside partial differential
equations.

Funny what you can do with "M". Variometers, Tesla coils, and such...
