[Phys-L] Re: entropy and electricity



The question is this: Is electricity pure work? As such is its principle
characteristic that it carries no entropy? (It does not even appear in an
entropy balance. See http://tinyurl.com/dyqao.) However, packets of
photons (electromagnetism) carry entropy expressed as s* = S/N = 4.97E-23
joules per Kelvin, where S is entropy and N is number of photons. [Bowman]
If so, then why should not electricity suffer from some of the deficiencies
of electromagnetic waves. After all, electricity behaves like
electromagnetic waves in a wave guide, does it not? Do wave guides
annihilate entropy?
