I hope Rosie Posie is taking notes!  lol

It's still drilled into me.  The impedance of a capacitor at zero Hz is infinity.  The impedance of a capacitor at infinity Hz is zero.

What is it....  Impedance = 1/(j * omega * C) = - j/(omega * C)....  something like that?   Multiply by j/j.

Great show guys.

Seriously now... thanks for bringing this up, MH.
Inductors of course behave in the inverse manner. So as one sweeps frequency for a given combination of capacitance C and inductance L, the inductive reactance will go one way and the capacitive reactance the other way, and there will be some frequency when the total reactance is minimized and the most power can be transferred through the LC network.
This is what I meant in the first cap video when I said that there was a frequency at which the cap seemed almost transparent to the AC power... but I was neglecting to mention the inductances, since I had not yet put them into my physical model.

Ain't that the truth...

I was looking on YouTube and there is lots more instructional material on capacitors and related as compared to a few years ago.  There are lots of serious teaching clips done on a blackboard and some computer whiteboard stuff also.  I am trying to find the one clip that would be the sweet spot for here but no luck so far.
