RESONANCE EFFECTS FOR EVERYONE TO SHARE

[gotoluc]

Thank you Groundloop for replying to TinselKoala,

I knew your 40 years of electronics experience would understand why I put the meter at that location.

Dear TinselKoala,

I know this is hard to believe!... I am doing my very best to give the most accurate measurements. A few posts above I explained to you why the meter is at that location. Also, just to not create confusion, the 50vdc capacitor is 4,000uf and not 6,000uf. The coils are connected definitely long enough that the 50vdc 4,000uf capacitor will need to draw some current trough the amp meter connected to the variac. I can leave it connected all day and nothing changes!... the draw stays the same. I though that adding the bulb in series on the positive side of the 50vdc 4,000uf capacitor was going to be enough proof (beyond meter) that no extra current is drawn when the coils are connected.

Welcome to Resonance, the forgotten Real Science

@gotoluc,

The switch should not have any problem with using 12VDC for both the switch side and the logic side.

Groundloop.

Oops, my mistake ... you are right of course. I had the coil unplug and forgot about it

It is so cool to see it work ... I didn't change any of the SG settings. I left the car dash bulb in series and connected the logic and then connected the switch side to see how much more it would draw from the bulb and practically no bulb intensity changed and the 2 6,000uf caps with loads charge up . The coil 1 10 ohm load cap goes to .80vdc and coil 2 5 ohm load goes to .47vdc

If someone wants to do the math my 12vdc SLA battery is at 12.33vdc

Well, OK, here's another way to look at it. You are charging 2  6000 mFd caps to 3.15 volts. That's a total of about 0.06 Joules.
Your h-bridge input current is, say, 30 milliamps RMS at 50 volts. You leave the circuit on for one second, by which time the receiving caps are charged to their 3.15 volts.

So, input is 50 x 0.030 x 1 second, or 1.5 watt-seconds or Joules.

So, even assuming your meter's numbers are correct, you have plenty of energy there to do the job, even with losses.

Am I getting the input numbers right? You are charging for one second, right?

So maybe we don't actually expect any extra current to be visible on the meter.

I decided to readjust the SG since I found that different voltages changed the resonance point of the coils and here are the new results.

With both, logic and switched side connected I can tune to get 1.72vdc on the 10 ohm load and 1.11vdc on the 5 ohm load from 12.29vdc but I'm not sure what to use as means to calculate the current draw I attached my good quality amp meter to it measuring DCma and it is drawing 126ma feeding both (logic and switch) and 49ma just logic alone.

We should keep in mind that that Resonance likes voltage and I think the effect are better with a higher voltage input. This test is only to better understand the circuit.

This is to address @gotoluc's concern but would be destined to all three. GOOD WORK GUYS!!!

It is not because we do not interject that we do not follow this progress. Actually, this is teaching me personally about circuits, cooperative progress and more. So please do not give up regardless of the final outcome. This is always a learning process and that is priceless. For me the circuit talk just is way above my head so I prefer to follow and learn. Most of the doers work on several projects at a time so please don't take it personally for not always acknowledging this or that. This is a collaborative process. You learn, I learn we all learn more from all the things we individually do and when it is time, we can use these experiences to help others in other ways. So good on y'all.
