Hmmm  lots of coils

I wonder,  if you have 2 coils, say 2mh each, if we put them in parallel, would the inductance change?

Im just guessing here, as I have not really seen many or any examples of parallel inductors.

Why would the inductance change if they were in parallel.

In series I can see a change, but parallel, im not sure.

The only reason I say this is because of Titos ingredients.

2 caps 1 diode lots of coils.

2 caps for a lot of coils?  I can only figure parallel.

Otherwise, many bifi coils so they are resonant to the driver, made of 2 caps, 1 diode, and "n" coils.

Titio the puzzle maker.  ;]

2 caps 1 diode lots of coils?

no switches?
no battery?
no transistors?
No antenna?

Hmmm,  the puzzle that has no picture.  ;]

I posted picture.It's Tesla Harpin circuit. Read text below picture.
I have two questions :

1. Is there a way to use electrolyic caps in harpin circuit ? If so then how connect them ? That would allow to test very small  circuit with small voltages like 12V even ! Tesla said it is possible but capacitor need to be huge (in capacity) and expensive. Now we have electrolytic caps which are quite cheap.

2. Can somebody post a circuit which allow charge harpin capacitors to 800V (+400V and -400V) efficently (meaning many times per second) ? I've build  for my circuit (described in amplification thread) a string of 1uF 400V caps and edn with 3uF 800V cap in harpin embodiment. Second problem will be to find electronic way to discharge this cap.

hey Forest

maybe the huge caps tesla was talking about back then, these days are not so large..   ;]
