Default The power explanation

This simple example that shows that existence of "reflected power" on a
transmission line does not necessarily result in some or all of the

I will leave it to Cecil to take to confuse this simple example with some
photon based complication.


No photons necessary, Owen. You are using a Thevenin
equivalent source. Paraphrasing Ramo et.al of "Fields
and Waves ..." fame: No valid conclusions can be
automatically drawn from the calculation of power
dissipation inside a Thevenin equivalent source.
(Sorry, I don't have the book with me for the exact
quote.)

For a lot of real-world sources, double the voltage
with zero current output would be very bad news.
