On the surface, this is all very correct, however, you cannot induce
reactance without inducing some value (albeit it may, or may not, be
trivial) of pure resistance (ohmic dc), barring the use of
superconducting material, of course.

I assume you are saying that lengthening a passive
element increases the ohmic losses? Then wouldn't
shortening a passive element, to induce capacitive
reactance, decrease the ohmic losses? And in either
case, since reactance reduces the induced current
and since ohmic losses are proportional to the square
of the current while only being proportional to the
first power of resistance, wouldn't that still
decrease ohmic losses?

Can people who live by the trivial sword, also
trip and fall on that same trivial sword? :-)
