When both batteries are on, the total power in the resistor is:

The intensity equation gets the same total power as you do. If
it's wrong then you are wrong. If it's right then you are wrong.
Seems that you are wrong either way. :-)

The difficulties with your explanations are not so much that they
give you the wrong numerical answers. In fact, they give you the
right numerical answers so often that they convince you of their
truth.

No, the problem is that they lead you to do other thinks wrong.

For example, in all your examples you now provide a circulator
because you think this is the only way to control reflections,
when in fact, all that is necessary is a source impedance that is
equivalent to the line impedance and there will be no reflection.

In other cases you claim that problems are insolvable because
insufficient information is provided about the generator. In fact,
all you need to do is use the source impedance to compute
the reflection coefficient and the problem is solved.

You claim that superposition does not work in a generator.

These examples are suboptimal outcomes that derive
from your explanations. Better explanations do not lead to
these limitations.

Of course, you keep providing examples where the numbers
work and these reinforce your beliefs. You need to temporarily
let go and explore the alternatives. You will find that the
alternatives work better, not because they necessarily
give you different numerical answers but because they free
you to solve more problems and provide more optimal solutions.
