Assuming that P = V x I, the power is 0, always.
This seems to be at odds with explanation that SGCL#1's power is
dissipated in SGCL#2's circulator load resistor since there is no
energy flowing at the voltage maximum.
Nope, a directional coupler can still separate out the forward
and reflected waves even at voltage and current nulls.
It is a bit early to move to the complexity of directional couplers.
I am still stuck on how energy can flow through a point on the circuit
where the current or voltage is always 0.
Using instantaneous Power = Vinst x Iinst, the power at such a point
must always be 0, leading to the conclusion that no energy is flowing.
So how does energy flow through a point in the circuit where the voltage
or current is always 0.
Is it that Pinst != Vinst x Iinst?
Or is it that there is no point in the ideal experiment presented where
V or I is always 0?
Or have I missed something in the chain of reasoning above?
