Here's a good quote from Chau (the theorist from 1971):

"Electronic theorists have been using the wrong pair of variables all
these years--voltage and charge. The missing part of electronic theory
was that the fundamental pair of variables is flux and charge," said
Chua. "The situation is analogous to what is called "Aristotle's Law
of Motion, which was wrong, because he said that force must be
proportional to velocity. That misled people for 2000 years until
Newton came along and pointed out that Aristotle was using the wrong
variables. Newton said that force is proportional to acceleration--the
change in velocity. This is exactly the situation with electronic
circuit theory today. All electronic textbooks have been teaching
using the wrong variables--voltage and charge--explaining away
inaccuracies as anomalies. What they should have been teaching is the
relationship between changes in voltage, or flux, and charge."

If this is a big to electronics as F=MA was to physics, then
electronics is about to experience one hell of a paradigm shift.
