What is the significance of (25/3)*4 ???
You seem to be under some misapprehension -- First solve for the network as if both ports were nonreactive -- then compensate the reactance in port #1...the reactance ration
how should the port 2 network solve or 1??First solve for the network as if both ports were nonreactive -- then compensate the reactance in port #1...
In this case 'network' refers to the two reactor network that will match the ports to each other -- Ergo 'solving the network' means determination of the arrangement and reactances of said reactors...how should the port 2 network solve or 1??
Hello,All you need do is calculate the values of reactances X1 and X2
I ask myself that same question several times a day! -- Occasionally I catch a (fleeting) glimpse of (what seems to be) genuine interest -- If he is sincere he merely needs to focus -- one can but hope...HP, if you don't mind me asking, why are you still wasting your time? You know it's useless to try to help him.
Prior to compensation (at least) an 'external' capacitor and inductor are required -- as explained ad infinitumHello,
OK, why there is two component can't we bother with one only?
There is no telling what 'reactor type' X1 will be prior to solving for the network -- the compensation requirement means only that X1 must subsume port #1's reactance (as, for instance, via an Xl 4Ω less --or-- an Xc 4Ω greater than 'called for' by the solution...X1 will be capacitor because 180 phase i.e. negative voltage will cancel the inductor voltage.
what is the use of X2??
In post #280 you said (As regards the necessity/purpose of two reactors):what is the use of X2??
Weren't you telling the truth???I understand this very well.
Perhaps the Socratic Method isn't the best teaching technique to use with RRITESH. Maybe a fully worked example with every step shown in full would work better.In post #280 you said (As regards the necessity/purpose of two reactors):

That's been tried several times -- there's no indication that it helps past the end of the example. A very painfully applied Socratic approach has seemed to produce results that at least lasted until somewhere just past the beginning of the next example.Perhaps the Socratic Method isn't the best teaching technique to use with RRITESH.

I disagree with respect to this impedance matching problem in process now. For example in post #188, a final result was given, but without ALL the intermediate steps explained. HP keeps trying to drag it out of him, but it isn't coming. I have always felt that the Socratic Method requires a fair amount of aptitude/talent, which as I have said in a couple of previous posts, seems to be somewhat lacking here.That's been tried several times -- there's no indication that it helps past the end of the example.

Perhaps you're not familiar with Ritesh's threads, but I cannot think of any methods that have not been tried and failed. There is certainly more to it than just an issue with the language barrier.I disagree with respect to this impedance matching problem in process now.

I think the language barrier is a factor in the pace of his progress, but after watching the lengthy unfolding of all this, I'm convinced there's more than just that impeding the learning process.
First off -- sincere thanks for your input! --- I don't feel he'll remember the technique unless he 'discovers it' for himself - that said, I am incrementally 'easing' the learning curve via 'narrowing of the field', as it were... (You'll please pardon the mixed metaphors!)Perhaps the Socratic Method isn't the best teaching technique to use with RRITESH. Maybe a fully worked example with every step shown in full would work better.
If he's sincere (quite despite my 'bouts' of exasperation, I tend to think he is) his issue is that of focus -- While he's clearly intelligent and motivated - he sorely lacks discipline...While, in my experience, such is well nigh 'readily' manageable in a personal setting -- It is challenging (to say the least) , albeit, in my opinion, possible, via a forum... Of course the language barrier is an added complicationI think the language barrier is a factor in the pace of his progress, but after watching the lengthy unfolding of all this, I'm convinced there's more than just that impeding the learning process.
Agreed -- and such has been my experience with others struggling with focus...A very painfully applied Socratic approach has seemed to produce results
Note that I didn't say that it has always produced positive results, however transient. Merely that it has seemed to work, at least on occasion, in the past.I disagree with respect to this impedance matching problem in process now.

FWIW I have personal experience with individuals presenting precisely as Ritesh -- Said presentation being that of one 'so enamored of the wonders of the world' that they find it impossible to dwell upon any single topic --- Stated otherwise; they lack the discipline to take a quantitative approach to reality...Perhaps you're not familiar with Ritesh's threads, but I cannot think of any methods that have not been tried and failed. There is certainly more to it than just an issue with the language barrier.
