Confirming the Delayed Lenz Effect

[kEhYo77]

@all
A little simulation of gotoluc's test circuit without the shunt resistor.
Apparently the phase angle between the input voltage and current stays the same no matter what I do in here hmm...
The bigger the capacitance the higher the output but the input is all reactive.

Hi Overunityguide,

I don't know what to think now ... can you answer this question. In a Series LC circuit (like below) where would the Voltage probe be connected?... where I have it or on the other side of the Capacitor?

Thanks

Luc

EDITED

I added the Schematic of how I had the probes (green and yellow) connected in the video demo. The difference in where I think there could be an error is the yellow probe could be connected on the other side of the capacitor.

Hi Luc,

Your schematic with the yellow probe and with your green one is the correct setup to measure. This is exactly the same setup as what your wattmeter uses internally. And that when you replace the yellow probe to the other side of the capacitor, you see the voltage and current in phase, is also logic. This can be expected due to the fact that you are loading your transformer with the 10 Ohm load. (this results on a higher power factor on your primary input coil)
So then again I think that your first setup is the correct one...

I also have an other question about the accuracy of your wattmeter, do you know what the accuracy is on lower loads? Lets say lower then 4 watts? I say this because I can remember that when I was buying my wattmeter, that the accuracy for the more cheaper ones was no so good at all, especially in the lower range < 4 watts.

I hope that I have explained the probes issue in an understandable way. And if you have any further questions regarding your setup, then don't hesitate to ask them.

With Kind Regards, Overunityguide

I agree. I am NoMorePetro from YouTube. I would also add here as I stated on YouTube that the voltage is lagging the current slightly less than 90 degrees.

Thanks kEhYo77 for doing this circuit simulation. It helps and is a very interesting result.

In my test there is an ideal Capacitance value for the meter to reach Zero Watts. Once reached by just adding 0.5uf the meter would start to show 1 Watt and the more you add the more it goes up. The same happens if you reduce the Capacitance from the ideal value.

Thanks for your time

Thanks Overunityguide for confirming if my first probe setup was correct or not.

The Watts meter I used is not a high quality item. It's made by Blue Planet and model: EM100. Maybe someone can find something online about its accuracy at low wattage.

Hopefully Thane can bring over his High Quality Power Meter so we can re-confirm.

Thanks Rick for doing this Spice Simulation of the circuit. Great job and idea of making a video of it.

I re-uploaded my video since I now feel confident with everyone's support that this was not an error in my part.
I added a link to NoMorePetro (Rick) Simulation in the YouTube video description.

Thanks again for everyone's support.

LUC,

IT IS MY OPINION THAT ONE PROBE OUGHT TO BE ACROSS THE 1 OHM SHUNT (CURRENT) AND THE OTHER ACROSS THE PRIMARY OF THE TRANSFORMER (VOLTAGE). NOT THE TRANSFORMER PRIMARY AND CAP COMBINATION.
