A 12VDC battery is sitting there with a 200 amp*hour charge. Are
you asserting that there is no concept of where the 200 amp*hours
came from? Please tell me you are not that stupid.

Consider the one second long transmission line with 200W of forward
power and 100W of reflected power. That requires 300 joules of
energy during steady-state. If the 300 joules was not supplied
during the transient state, then it must have magically appeared
out of thin air in violation of the conservation of energy principle?
Is that what you are trying to tell us?

Cecil,

You can wave your hands all you want, but it won't have much impact on
the correct math and physics.

Try writing the appropriate equations for your puzzler, in steady state
conditions, and then figure out where to insert the transient behavior.
Good luck.

This is basic stuff taught in numerous math and technical courses. If
don't accept the basic math, then I guess we will not agree.
