Gosh, have you ever said anything nice to anyone?

John

GOSH, do you always hide behind such a bullshit facade?


Thanks for the prompt answer.

QED would have involved less typing ;)


I was being nice.

THAT'S the facade, dumbshit.

Gosh, you don't even know how to *pretend* to be nice. Check out a
Miss Manners book or two.

Cursing at me results in my disbelief in you having any ability, and
proves
a serious lack of maturity. Save it for some ten-year-old you can
impress that way.


Fuck you and your beliefs. I don't need to respond to your petty
baby bullshit at all. Nor do I need to measure up to your petty baby
bullshit assessments, dipshit.

So fuck off, jack-off.

Describing yourself again potty mouth?

I think the moniker "MassiveProng" must be short-hand for
crowbar-up-ass ;-)

MassiveProng == MassivelyWrong


Best yet. Let's us that from now on.

Your group? You're about as outsider as outside gets. By choice,
apparently.

For age multiply your retarded figure by 1.5 orders of magnitude.
For IQ, two orders of magnitude.

And the beat goes on...

Near Walton on Thames station afair.

Strange. I used to do the long commute from Hampstead
to Decca every day, and then back again. I didn't
have a clue what Walton was like.

I'm not impressed. I don't trust any article on transformers that
doesn't include the transformer equations

V1= L1. dI1/dt + M. d I2/dt
V2= M. dI1/dt + L2. d I2/dt

Modelling a transformer as an "ideal" transformer plus leakage
inductances doesn't give the same insight, and it certainly
doesn't give you the right insight.
Click to expand...
I think I disagree with you there Bill. Look at the
similar thread running here on leakage inductance.
The equivalent circuit developed to include winding
resistances produced exactly the same final sums for
Rpri and Lpri as the textbook sums that started off
from mutual inductance. In fact that was the check
that the equivalent circuit was correct.

I prefer an equivalent circuit because it allows an
intuitive view of which of the various transformer
imperfections are going to matter most in the
particular application.
