Default what happens to reflected energy ?

I have listed a number of the laws of physics that you are violating.
Of course, energy and power are different. Consider an ideal LC
oscillator at the instant of time when the voltage on the capacitor is
maximum and the current is zero. The energy is certainly not zero and
can be calculated knowing the voltage and capacitance (assume 1000
volts and 1uf). Yet the instantaneous power is zero because the
instantaneous current is zero.

energy = (V^2*C)/2 = 0.5 joule

power = V(t)*I(t) = 0

Please prove a one-to-one correspondence between energy and power. How
can you possibly say that you are tracking all the energy when the
power equals zero and the energy does not? Good grief!

I am not sure where you think there is an error.


Again, you need to cut off your output and enable your inputs. There
are no waves during DC steady-state. Therefore, there are no forward
waves and no reflected waves. Therefore, you basic assumptions are
invalid. For waves to exist there must be acceleration and
deceleration of carrier electrons and such does not exist during DC
steady-state. Why don't you know that?
