STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

It should be other way round. The practical minded folks look for input and output. The scientist would verify the OU from the system's point of view.

you are most welcome blue planet you can now remove my quote too as well

[blueplanet]

I have removed the last sentence in my last message. Thank you for your reminding me.

Blue Planet such bold claims call for a name and description of such a said device. Anyone here could lay such claims to "seeing a real OU device before" but as you well know without zero description, zero anything except for a claim of seeing you tend to lose your credibility with such a post. If you don't care to share that is entirely up to you but it is in your best interest if you do not bring it up for your own sake.

If you do plan to share I would suggest starting an entirely new thread so you do not hijack this one as I kind of am already.

The first picture is from Hyperphysics which shows the real formulas to calculate using instantaneous values.     

The second shows how RMS is used with cos angle to get real power.

Hyperphysics and college level literature should always be used before wiki. Vet

The hyperphysics formula is in terms of Vm and Im (the peak values) and it is for pure sine waves. Omnibus is not using Vm or Im in his calculations and does not assume his trace to be a pure sine wave, it can be of any shape. The wt and phi terms are taken care of automatically when you integrate samples. You have learned a lot about power formulas, now its time to go a step beyond and learn about basic integration.

The area below the curve of V*I gives the value of power, no matter what the wave shape, phase or peak values are, this is as simple as this.

The real question you should ask is whether its ok to deduct the I^2R term from the Pin, without first measuring the heat from first principle. It is a big assumption and a bit of gamble. Of course, I'm doing the same, following Steorn's method. So I'm also faced with this question. Steorn did the calorimetry but its a bit shady like all their stuff.

Here are the promised energy-time plots for the different conditions. This first one is for the above-stated R in series with  a 115pF capacitor:

This is interesting. How did you arrive at that particular value of C ?
