odd then that you shy away from any and all detailed technical
discussion. Hell, you admitted you couldnt even follow (ISTRIW) John
Fields simple analysis of a rectifier-capacitor filter.



Well .... considering his 'analysis' gave the wrong answer !

I understand it perfectly actually thanks. Fields was as ever just trolling for an
argument.

Funnilly enough, I was thinking about that example earlier today. I'm sure he's got
his sums wrong somewhere. I may return to this with an mathematical analysis of my
own. That's he's wrong is readily shown with any simulation btw.



I didnt study his analysis in any detail - because I really dont care;



Likewise. I'm way too familiar with the 'right answer' to need to have to examine
something in detail that he's only bringing up as a stupid troll.



I seldom if ever use mains transformers, and never for any power level
above a few watts, making anything but the crudest analyses unnecessary :)

when operating a cap/bridge from mains, resistance doesnt really enter
into it, but inductance sure does.



Why do you say (winding) resistance doesn't enter into it ? It's very significant with
typical line frequency transfomers !


I'll give you a clue: "when operating a cap/bridge from mains"



Barton has a seriously detailed exposition of the humble
rectifier-capacitor filter (one chapter worth), if you do it properly
its surprisingly complex.



In detail, I have absolutely no doubt.



I just find it frustrating that you often answer posts a-la this thread,
and seldom (if ever) provide any detail whatsoever - I dont recall
seeing any detailed analysis from you, on any topic. IMNSHO those who
can, do; those who cant, generalise.



Some ppl love to 'show off' with their calculations. I don't see the point where the
answer's so obvious.


a highly nonlinear circuit like a rectifier/cap filter is "obvious" ?!

I suggested simulation btw. That'll show anyone the answer without
them even needing to understand the maths.


LOL! I make a living out of fixing messes created by people with simulation software and little or no understanding.

but you consistently waffle, and essentially never back it up with theory - ascii schematics, maths etc. Hence my (perhaps erroneous) conclusion that you are lacking in those skills.

Hey, did Mr Ham get a simulator for xmas?

Ha, my kid had one of those when he was in the trade schools.

I would rather find a mistake of my own that I made and not pound
my head for hours to find one that the simulator made.
