Hi Chris.First off, please qualify your OWN meaning of "ideal" inductor?
An inductor with purely inductance, no DC resistance & no stray capactance? Is there such an animal around??? You may as well tell us
how to design or where to get an "ideal" amp with zero distortion &
zero time-delay!Secondly, what is R "theta". R is always linear, no vector angel! My goodness! I must have missed a lot. Is there such a vector R around???
If you want to involve the vector angle of the stray capacitance, spit it out clearly, for the sake of those less knowlegeable than you.Thirdly, what is "ideal" inductance? Inductance itself ia a magnitude
qualification of an inductor or a coil, in simple language, unit 'henry'. Are you telling us an inductor comes with X "ideal" henries & Y "unideal" henries?IMO, it is your over"guesstimating" or confusion or what? One can get
this basic electrical knowledge from high school. Otherwsie, I got
to re-study my electrical engineering discipline back to college.WE can't read your mind right every time. Please present your lofty ideas precisely & concisely. On behalf of whoever read your posts, thank you.
Good 'sober' thinking & listening

Jan 30, 2004.PS: I have told you the formula of calculating impedance. Did you read? Nobody is infallible. If it is an error or overlook, just admit it. No big deal. Please don't re-direct attentions. It won't bring
you anywhere.

I was referring to 2 different ways of notating complex numbers - (radius, angle) or (real, imaginary).Example: (1, 90deg) in (R,theta) form = (0, 1) in (real,imaginary) form.
I thought you were familiar with that notation. My bad.
Now, as for the impedance of a 10H inductor with 50 ohms series resistance, the answer I was looking for was (7539, <89.62deg), which is equal to (50, 7539). Most people will agree that for first order approximations, (7539, <89.62deg) can be represented by (7539, <90deg).
So you learned all this in high school? Wow, must've been some good high school. All I learned was Ohm's Law in High School.
As much fun as this exchange is, I feel we must call it quits. All of our arguing has boiled down to misunderstandings due to language differences.
It's just tube amps, after all.
See ya,
Chris

Hey hey,Calm down... :-D
Don't argue over the last decimal - as long as one is right within 5% that is high quality.
I know "cheap-jack" is a dickhead, but to argue - no matter how tight one are - is a perfect waste of time and effort...
Where will the world end if everyone is nitpicking?

So, "dickhead" is the "nature" English yuor nom teaches you. Right?
I wanna tell her "Par" english" is so fu.k..g "unpossible" !!!!!
