capacitor datasheet? ripple current ? Impedance ratio?

Hello again, Phil Old Cussin Buddy. A couple messages ago, I asked you a question about your possible possession of firearms. I have a bet on with me mates here. Could you be so kind as to answer the question in your most polite tone?

Hi Martin!

This is 'John Chesterfiled Fields'.

Nothing new..... :)

Now do it properly with differentials !

Cough Splutter !

Good Lord !

Graham

And how is it done in the real world ?

Graham

In fact you were no help at all.

Now tell me, why would 2 caps of otherwise similar size etc have quite different ripple current ratings ?

Graham

"Eeysore"

The rule works out just fine when the p-p ripple voltage is under 20 % of the average DC value and the ripple frequency is only 50Hz to 400Hz or so.

It just a simple transposition of the capacitor formula:

I = C . dv/dt

Long as the discharge is linear over the time interval ( dv/dt = k), the formula holds.

BTW

T = discharge period, not ripple period.

....... Phil

I just wanted to wind him up !

Agreed.

Graham

Thanks.

No. Have I placed a time-trial, or an expire-date to the thread? I use a digital machine and an offline Newsreader. Where is the problem?

It is not forseenable, when all the News of Usenet will be deleted irrecoverable.

P.S.: Hint.... 'Paradoxon'

--- The problem is that you're dishonest and you're trying to change the subject so you won't have to deal with the issue at hand, which is that you can't figure out how to get a 3 digit LED display to display "333", while at the same time trying to set yourself up as some kind of guru who has access to unconventional knowledge.

Unfortunately, (for you) you still haven't figured out the vagaries of American English, so you come across as bogus. Just as you would, I'm sure, even if you were fluent in our language.

Gurdjieff you ain't.

--- Another one of your "gems"?

sounds like Coprolite to me.

C'mon, I am making the first Thread into sci.electronics and you hack on me about.

That was just of interest for me. In another NG, though.

P.S.: You are dishonest! And surely not the reference in sci.electronics.basics!!

Michael Terrell is better.

Kind Regards,

Daniel Mandic

I cannot dance :), mei!

P.S.: open a new NG... sci.electronics.competition

Ok, John, just how big was her "Chester", and why did you "filed" it?

yeh.... why did you file it, John. (:))

Best regards,
