Almost as fast as I turned the computer off, that I realized what
needed to change. The definition of Ohm's law becomes a physics law
once we remove the idea that R is resistance. It is not resistance in
terms of heat or friction or anything else. What R is, is the number
of turns N, the number of windings in the wire in the Faraday law. So
that if we write Ohm's law as V= iN we end up with almost the same as
Faraday's law except the direction of current flow.

Now in the above I realized that N in Faraday's law was R in Ohm's law
and that it has nothing to do with resistance but rather how much
current can flow by the number of windings.

And also, I separated the lines of the 4 Maxwell Equations so as to
make easy to see how adding them together yields the Dirac Equation.
In fact, the 4 Maxwell Equations is a far larger generalization than
the Dirac Equation, and what I mean by that is that there are extra
predictions accruing from the Maxwell Equations of true physics that
the Dirac Equation could never predict.
