The math is pretty easy, Roger. Keith seems to believe
that an inductor stores power which is, of course, a
ridiculous concept.
You must have misunderstood. The power measured at the
terminals of an inductor is the rate of change with respect
to time of the energy stored within the inductor.
In calculus terms, the power is the derivative of the energy
within the inductor.
This is equivalent to the rate of flow of energy into
the inductor (or out of, if you choose a different convention
for the sign of the value).
