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

Here, we have the same R but the capacitance is 64pF. Notice the negative slope of the input energy curve. This shows returning energy to the source (in addition to the production of Joule heat shown by the red curve).

And, here, we got the resistor R alone in the circuit (no capacitor C):

I am by no means an electronics genius I will be the first to admit...

But that looks like a fairly simple thing to build...

I do have some questions about it though.

Resistor (R) is at the top on the right the banding on the resistor should face north right? And what is the resistor specs and where to buy.

The capacitor (C) the negative lead should also face north correct? What are the specifications and where can I purchase this as well?

The pulse generator what type of pulse generator is this where can I buy it and how many legs and how does it solder into this circuit as well.

Where is the supply current coming from and what is the supply current and voltage and the supply is hooked to the pulse generator correct?

I am interested in testing this fairly simple looking circuit...

CH1 and CH2 are both leads of the current probe I would assume as well. So I may have failed this basic electronics course so far but learning does not come without failure.

If you will I would love to know the exact specifics on building this circuit... I may just have to find a scope for purchase and start doing some math as well boooo! I always hated math. heh

anyhow I thank all of you for your comments that leads the the making of a good thread with much to be learned this seems to be a fair starting point for many this simple little circuit will help others understand circuits while it is not the standard denotations or pictures if you will for the parts in the circuit which is like a whole language to learn in itself it appears it is a good starting point.

Now we are getting to the real crooks of the problem. Let me quote some of wikipedia on rms power:

http://en.wikipedia.org/wiki/Root_mean_square#Average_electrical_power

So this is really like the chicken and the egg problem. But in our case the mean is much stronger than the root mean square. The latter is just a by product of the former if you follow some assumptions. The P = R*I^2 asks you take the mean of I and then square it. This is coincidently called rms. The problem with using rms values with non purely resistive circuits is that you could have 0 REAL power yet have substantially more apparent power calculated from these rms values:

http://en.wikipedia.org/wiki/AC_power#Basic_calculations_using_real_numbers

This is due to the inherit way root mean square is calculated by starting from a resistive energy point of view. That is why it has to be corrected by using impedance knowledge.

However if only instantaneous power and its average/mean was used you will always be safe and get only REAL power out of your average formula of power (P=U*I). Because you are not starting off by assuming you have resistive load and calculating the rms voltage and current. This is fundamentally calculus. By integrating over an arbitrary function you get the average area under that function, then by dividing by the length of the area you get the average height.

Has all doubt been cleared now about the calculation?

Broli, Thanks,

I do agree now we are getting to the real crocks of the problem. Actually, I was wondering what was the source of your misinformation.

Wiki, is a quick source of information, but you can't trust all information because they let almost anybody submit. They didn't require that an EE write what you showed. I do quote from them sometimes but only if I know from other accurate sources that it is correct.

The comment in my last post that I made about RMS is from college level literature. Omnibus, I didn't specify any formula about calculating power using RMS. I have in previous post and used the real power formula shown below.

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

Now, let me also reveal the secret of the transformer coil yielding the OU effect. Look how it is wound. Isn't that something? I've established that it not only must be wound in this way but has to be of a certain length to generate the OU effect. Recall that I showed an even bigger OU effect with a coil wound the same way but made of longer wire. The length must be just right though and one won't get more OU just by adding length.

So, all this talk about the importance of cores and what not goes. Things turned out to be as simple as can be. I guess all of that was overlooked not only because it didn't occur to anyone to check the power balance at various frequencies etc. but because accessible (and not only accessible but in principle) equipment to do such studies has not been available in the not so distant past.

Notice also this--all the OU is of electrical nature and we don't even need to generate heat from current. All the OU can directly be stored in a capacitor and then through a converter brought back into the input. I'm sure there are designers of electronic circuits lurking here and it would be of great help if someone find the time to design and make such converter. It seems to be it would be a trivial matter for an expert in electronics to do that but I may be wrong.
