Coil mystery - need help

[boguslaw]

I need to compute energy stored in coil depending on time of short-circuit it with DC source of power.
The idea is simple : to connect high self-induction coil to DC source (battery of give capacity ,voltage and power in impulse) for a given period of time and mathematically compute the energy released on disconnect and voltage of flyback thus generated.

Is that possible ?

I know that em=L*dI/dt and e=0.5*L*I^2 are basic equations to compute electromotive force of self-induction and energy stored in coil but how to apply it to the time and power source in short-circuit ?

Can somebody help ?

He he nobody is willing to help ....
Nevermind I solved it.

But you can help a bit if you know in which part of period of oscillation in LC circuit energy is stored in coil and in which it's stored in capacitor ?

Q1: I don't think i understood the first question. How did you solve it?
Q2: Is this a trick question?

No. I realized what Tesla did and it's very important to see it.
There is only one LC resonant circuit , forget about parallel or series - those are because of connection to power source which MUST BE efficiently eliminated.That's the key and that's why there is the same equation for resonant frequency for any LC circuit - because there is only one and IT HAS TO OSCILLATE FREELY.

Let the swing be going and use only a little push, NO CONNECTION TO POWER SOURCE - power source is a FRICTION MECHANISM .

Tesla did it with 2 (actually 3 but you have to find why) resonant circuits joined together and that's why he called it - "make & break"

In today words : while forming separated parallel resonant circuit you have to form also series resonant circuit which eliminates power source interruption for the former and allow to give it a "kick" which rises amplitude up to the infinity. When LC circuit cannot stand up that it throw out excess power or simply burn out if you not allow him.

I have come to the same conclusion, its all a matter of perspective.

I think you have to expand on this, maybe also throw in a circuit diagram?

I think you have to expand on this as well, maybe also throw in a circuit diagram here too?

APPARATUS FOE PRODUCING OZONE - Google Patent Search

Find 3 resonant circuit there

How fun!
But I fail, i can only find the two obvious ones

A third within the motor? (i guess there is a motor or something)

[boguslaw]

Actually ozone patent was not so good. It may have 4 resonant circuits though 3 are important only I think

1 is obvious - capacitor and a coil of only few turns in parallel
2 - capacitor with coils of motor - in series when rotary sparkgap disconnects 1 one

3 - coils of motor with capacitance of power wires and power source in series ; when 1 circuit is closed that one also is closed charging coil

4 - it may be secondary with plates of device generating ozone but that one is not important

1,2,3 have to be in "harmonic perfection"
