The step function from zero to DC contains a lot
of frequencies. I suspect photons are involved
at the leading edge of the DC pulse.

"Suspect" -- Perhaps like Inspector Clouseau?

Humour aside, for transmission lines you should
stick to charge, and distributed capacitance and
inductance. This model is aptly capable and has
no difficulties as the frequency drops so low that
it becomes indistinguishable from DC.

Why bother with photons? Only at the leading
edge, you say. What explains the rest?

Where is the energy stored? In the capacitance
and inductance. Why not use the tools that work?

Why try to force fit photons?

If we look at a tree from the north side, and then look at the same tree
from the south side, we have looked at only one tree but we have seen it
from two perspectives.

Zo = sq. rt. L/C = 1/cC

Inductance can be described as L = 1/((c^2)*C) (inductance per length)

So is the energy stored in the inductance or in the capacitance.

Two ways of looking at the same tree.
