but those are not the same type of electric fields.
From our analysis it appears that the electric field in Ohm’s law (7)
must be something else than the electric field defined by Maxwell’s
equations (1 – 6). In particular, it should not be confused with the
static electric field as defined by (1) and (5) which is very obvious from
our result in Sec. 2.
The microscopic picture of current flow suggests that electric currents
should be conceived as moving electrons which are accelerated by an
average field and stopped again by collisions. Each electron produces a
magnetic field according to (2) and (6) which varies in time. As a result
fluctuating electric fields are induced according to (3). On
average these fields seem to add up to a quasistatic macroscopic field
which ultimately enters into Ohm’s law and may be expressed as the
gradient of a potential. This is, however, not the electrostatic
potential which is produced by a charge density according to (1) and
(5). The divergence of the average macroscopic field in Ohm’s law
should, of course, vanish – in agreement with (10) – as it is a
rotational field created microscopically by induction

are you talking fields or circuits ? the resistance or impeadance of
free space is 377 ohms, Zo = sqroot(muo/eo) Maxwell uses muo and eo, in
his equations, but that does not apply to electrons jamming into
particals and restarting up again like in a resistor

you are applying EM to resistors, no can do.
if Feynman said that he is wrong.

gravity is not EM
