Stubblefield coils (bifilar) and speculations

[Pirate88179]

@ All:

I just checked my coil outside today and the numbers are still pretty good and holding as follows:

.94 vdc
1.3 vac
68 mA

Here (should be) a picture from yesterday's tests.  You should be able to see my buried coil.  This test was made using the carbon rod for the + and the core of the coil for the -.  (This site is really hanging up today, I have been having problems posting anything) This shows 1.32 VDC.

This shows 1.9 volts AC.

This shows 47.2 mA.  It is much higher now  (68 mA) and had continued increasing yesterday after this was taken. I hope it is higher tomorrow. Note: this reading is taken from just the coil only between the core and the cu wire.

I just noticed that you said you were reporting numbers for voltage across the 5cu wire and the core bolt. Is that what you have always checked?  not between the 10's or 5.6?

Maybe I need to learn how to read?

I checked mine in spite of the snow. (It melted off already.)

So now, just for the dc voltage, the dcvoltage was higher on 3 out of the 4 but lower on one of them. I wonder if it is cycling very slowly? what if the frequency is under 10 cycles per MINUTE or HOUR?

When I was playing with the sliders on that RLC chart, I noticed that when the resistance was too high the oscillation would stop.  After one spike the curve would  just slowly get lower over time.

What if this is what we have?

Any EE's want to venture a thought? like how we would find out?
