@Mk1

Humm I do not understand AC well enough to have any type of intelligent conversation about it I thought current was current? Am I wrong? Please forgive my ignorance!!

Take care!

MK1 said he did not want to spend time arguing about it. Why don't you let it be?

I like to call it a free ride.

Picture the farmer delivering a load of hay. Once it is delivered, the horse still has to pull the wagon back to the barn.

If you hop on top of the wagon, the horse would have to SEE you to even notice. You weigh less than two bails of the hay that is gone.

So, it is NOT without cost. Ask the horse as he climbs up the last hill, but it is no more than was there anyway. That is why I call it a free ride.

@all

I am sorry if I upset anyone. I was simply curious and trying to have a better understanding.

I am very sorry....

like xee2 sayed, the results is not 1 amps in each of the 3 coils.

currents create magnetic flux and the magnetic flux is passing through all the coils.
that mean the currents is passing through all the coils no matter how many coils there is.
this is a known physic faq.
does that mean ou ?
it would be true without what Lenz discovered about induction.

the results depend on the impedence of each coil and the impedence is affected by the load.
and this is a good thing.

once a cap is charged, it won't affect the other coils...




@jadaro2600
making the jt with multi coils is not a must do thing.
all depends on what you make it for.

litz wire for low lost at high frequency. <-- btw, that is form of multi coils.
single pickup for very high potential.
multi coils for testing cap discharge theories.
etc...

just build to the specs you need.
