Heh, heh... Electrodynamics...

Circuit Electrodynamics:

In the beginning there was Circuit Theory [Ohm, Kirchoff] which was
found wanting....

Field Electrodynamics:

Then there came Field Theory [Maxwell, Heaviside], which was found
wanting...

Quantum Electrodynamics:

Then there came Quantum Electrodynamics [Einstein, Pauli, Schrodinger,
Dirac, Feynman] and to date... nothing is found wanting...

What, exactly is your problem?

Circuit Theory, Field Theory and finally Quantum Theory are all evermore
exact
models of the real world.  For many problems Circuit Theory suffices, but...

For those knowledgeable... they move from Circuit-Theoretic models to
Field-Theoretic models when the situation warrants, and they move from
Field-Theoretic models to Quantum-Theoretic models [QED] when the
situation warrants...

Don't use QED as the infrastructure of a Spice program and don't
use Circuit Theory as the infrastructure of an NEC program!

An Engineer is...  a person who knows how to model efficiently and...

When to change models...

What?
