Flyback transformer design confusion!!

Sorry I reposted your post above without adding what I wanted to write below. The point I wanted to make was the error seems to affect your whole expression for power, doesn't it?

It does only by adding in " a multiplied by w" . But the integral is still zero as w is not a time dependent variable. Which still makes the average Power null.

Yes, electronics engineers are well aware that -always- Power=Vrms*Irms since that is what rms is specifically about. However if you do not understand the derivation of the relationship between voltage and current then you will be relagated to your silly high-school math and drawing rediculous conclusions based upon your ignorance.

Connected to my sinewave generator I have an ammeter in series with an inductor and a voltmeter across the inductor. Both meters are set to read rms values. At the appropriate frequency the ammeter reads 1 amp and the voltmeter reads 10 volts. I know that Power = Irms*Vrms.

Using this information I thus calculate that the power developed in the inductor is zero.

Oops I forgot to mention that to calculate the power I need the rms current of the inductor, not the sinewave generator, which means that I needed to measure ..........

But I am sure you know better.

If you can prove that I will be happy to correct your attempts.

Go tell your boss that the power is 10W. Assuming he is minimally competent I'm sure you'll be looking for a new job.

Or should I say your school teacher.

I sure do.

Oh dear Charles. Methinks such a subject is a bit beyond you at this time.

Just ask anybody who knows anything about electronics about the power developed in reactive components (inductors and capacitors to yourself). Better still look in an electronics for beginners book and try to understand what is meant by Phase Angle and Power Factor.

(PS my boss does the cooking and even she knows cos90=0)

I see you did just that. Good boy.

Oh so my suggestion was great . You finally admit that you didn't know what Power is.

Yes your boss is right .

The above was your assertion . Now you have changed your mind! Which means you have finally learnt something from me.

Send me a cheque for that.

There are those that know what the construct of Irms is and those that don't. Many use the 'shorthand' Irms that is the root of the sum of the squares approach as being what 'current' is without a full understanding of the concept of voltage and current.

Some that do understand tend to be floppy about the use of volts and current -making the assumption that the meaning in that instance is obvious as to how it is being used.

I am sorry Charles but you have a *very* long way to go before you get cheque.

You showed to us you don't have an understanding of what the concept is by confusing Cosines with rms values. So just go troll elsewhere with your garbage.
