Understanding electricity in the TPU.

IST,

Great Idea!!

I will try that as soon as I get my cosmo's meter back from service

i have years ago done this ...    mr . m  i offer you a clue ...  i hate giveing answers tho ... 

peontical diffrence....

current flows from positive to negative in both cases.

Why?..because thats what my DVM and compass say lol.

I know the theory about electrons flowing in opposite direction to the current.

Could it be because your DVM is in a different frame of reference than what your measuring?  The hands on a clock will rotate CW when you're looking at the face of the clock.  If you looked at the back side of the clock then you will be measuring the mechanism that moves the hands which will be moving CCW. 

So, will we say the electron and current flow is in opposite directions if the hands (electrons) move CW in the front-side frame of reference, but the mechanism (current) that moves the clock hands is moving CCW in the back-side frame of reference.  Of course not, because the hands (electrons) and mechanism (current) are moving in the same direction relative to each other in the same frame of reference, but are not moving in the same direction relative to different frames of references which is the front and back of the clock. 

Electron and current flows from negative to positive when leaving a source, and will flow from a 2nd source from the negative to positive to return to the first source.  There are two sources or two EMF's involved and they are a mirror image of each other, thus in different frames.  Between the two EMF's is a zero point.  As you move away from this zero point in separate directions, the voltage will be increasing.  It does not mean the electron and current flows in opposite directions.  They are the same thing.  Electron flow is current flow.  Your DVM is only reading the potential difference between it's terminals, it is not reading the potential difference that is outside it's terminals, which will have a different polarity than your DVM.

torriod now singing 6-10khz at 36.04 k

driving pure sine at +10dbm

the cro shows the spot  as phase distortion on either side +/- a few hertz  and the sweet spot is back to sine .
A magnet sets off the singing.and is sensitive to it from a few feet away Nothing I would call real power yet. But this is most interesting.

I will post some pics when i get this thing tuned better.
@EM
I am interested to see your input drive if you have time

Color does not say anything.
It can be diffrent when you order somewhere else.

If you mean different manufacturers' mixes, you are right. But in this case with Micrometal toroids, Mannix is right.
