Here are some pictures of the setup.

Omni,

First reaction that anyone would have is - you have OU !

Now, it confused me for a while because this is an unexpected result, so I decided to dig more in the data. Below is a plot of instantaneous resistance with the input current (scaled by 7000). It should be obvious that the resistance will not change in reality, these values are derived from AC voltage and current, so they are wrong. But thats not the point. But we should see a constant actual value of resistance during the DC part of the pulse, when the voltage does not change. However there is no such part here.

When a pulse is applied to a coil, there is a transient stage and there is a steady state. The instantaneous power in transient stage is expressed by a different formula, in steady state its simple I^2*R. You can see from the plot that there is no steady state portion here in current. That's because the frequency is so high that the pulse ends before it reaches the steady state. So the energy calculations are incorrect here, IMO.

That is still an useful experiment, because, we learn an important thing, that your method is applicable only when the rise time is much less than the pulse width.

May be I'm making a mistake here, so a second opinion should be nice, may be teslaalset can point out the exact problem, if he is here.

@Omega_0,

Thank you very much for your analysis. You know how much I appreciate your input. I'll have to reevaluate it and get back to you. I'm considering submitting a text to a peer-reviewed journal and I'll let you know what the outcome is.

Omni, Omega, I'll check as well.
But I have to catch up some reading, because I've not been following in details what progress has been made by you.
Please, allow me some time.

You are welcome....
Peer comments on this method of measuring pulsed energy would be valuable. I guess no one has peer reviewed steorn so far. Unfortunate that.



Teslaalset, I made a separate thread for my replication when you were away. Hows your replication going ? You have the holy Metglas, throw us some bone please.
