I think so, but maybe with the resistor this could be done with just plain dc, or pulsed with the same frequency you pulse the transformer.
The important is that you block the electrons in the resistor.
I the water i think we can do basically the same thing, for example if we make the static positive voltage to be the negative electrode when electrons wants to flow from the negative to the positive they will be attracted by the electrode the are coming out of. The field will hold the electrons to a certain degree.
With the choke is the same i think but he might have matched the coupling inductance and resistance of the wire to obtain the right parameters. I think that if this is true he only made the coils to complicate and take everyone out of track. The important is that the VIC become a charge pump of current source, this way it has very high output impedance.
I think this is easy to picture, you apply positive and negative from two different supplies on each side of the resistor, if the voltage in the power supplies are the same, no current will flow thru the resistor, only between the power supplies, this mean that we simply need to find the right ratio of resistances to allow to block the current so the vic can get high voltages.
I think that maybe no power will be dissipated on the resistor, or maybe just a little. I think that a 2,5ohm resistor would be enough, maybe applying 5v 2 amps we restrict the current.
Thing is we need to block the current so it can't leak into the power supply. I trying to understand how to do this, cause even diodes will not block i guess.
It might be a current source thus having very high impedance as to not allow the current from the 1° power supply to leak into the second.
I will work on this today and later i will show you some drawings.
Your question about the frequency also raised me a question like what if i pulse the resistor with a high frequency for having kind of impedance also created because the current is being interrupted or modulated at a high frequency,,,
Many many things to think about.
Tomorrow is the first day officially in the university. = )
