Now for the real question. When the net instantaneous
power is 0 at a point with non zero power on each side
of that point, is any energy transferred?

The answer is - of course - equal amounts in either
direction.


So you seem to be claiming that the following two
statements can be simultaneously true:

1. Power [recall p(t)=v(t)*i(t)] is the rate at
which energy is transferred.
2. Energy can be transferred when the power is zero.

To my simple intellect, one of these statements
must be false.
