How much current flows into 400.000 ohms?

Let's take a look at a simplified system. The SGCL source is
a signal generator equipped with a circulator and load resistor.
Each segment in the following 50 ohm lossless coax is 1/4WL long.

|--------1.25WL 50 ohm coax-------|
200W SGCL------A------B------C------D------short

The signal generator is sourcing 200W and the circulator load
resistor is dissipating 200W.

What is the net current at the short and at A and C?

What is the net voltage at D, B, and the source?

What is the forward power and reflected power?

What is the net current at the signal generator output?

What magnitude of current is the signal generator sourcing?

What magnitude of current is flowing through the circulator
load resistor?

What is the phase difference between the forward current and
reflected current?
