Default Current through coils

From the beginning, then:

As we have seen, if the whip is loaded by pure inductance only, there is
no change in current between the two terminals of the inductance - but
there's a big step increase in voltage. At the upper terminal, the current
is the same but the voltage is very high, so we're into a much
higher-impedance environment.


Reality check here. I need explanation how the above could happen. "Current
stays the same ... and the big step increase in voltage." As far as "idiot"
professors taught me, (current x voltage) = power. So, am I to discover
that the pure inductance is better than perpetual motion amplifier of power?
More power coming out of the coil than going in? Eureka!!! How could I
overlook that? :-)


Your professor would have told you that you "overlooked" the phase shift
in the voltage.

The rest is just more of the same kind of name-calling. You didn't
really read what I wrote, and you don't really want to hear any answers.
All you really want is a shouting match. Well, tough, you don't get one.
