As A Pre Teen What Did You Want To Be When You Grew Up?

A Scientist.
(I eventually became an Engineer.)

@Hal Pollner, does eventually mean you were a scientist before becoming an engineer?

 

What field of engineering?

 

Maybe a train engineer?

 

@Bob Kirk
I look forward to his answer; he usually ignores my questions!
Frank

 

Same as Thomas and Beth

 

No, it doesn't.
Hal

 

@Frank Sanoica , he did it again.

 

@Shirley Martin

Proly recognizes my Polish heritage, and acts accordingly!

Proly knows when he's whupped.

Hold it right there, Frank Sanoica!

I never ignore your messages!
In fact, I enjoy and respect them more than anyone else's, because we're compatible in our interests, hobbies, likes, and dislikes!

So there!

Touche, then. While we're at it, then, I'll try to recall the unanswered questions:

E.E. Math: E (sub-L) = L di / dt; where did 63.2% of total current change represented by one time constant come from? If resistive, t = R C. All inductances have resistance, pure inductance does not exist.

Gee, I can't think of the rest.

Frank

 

You're talking about the "Q", or "figure of merit" of the inductance in question.

The "Q" is represented by XL/R. or Inductive Reactance divided by Resistance.

An inductor with NO ohmic resistance would have perfect Reactance, and this is never found in real situations.

I can't answer the time-constant question, because It's been so long that we've had to use it in electrical math problems.

HEY LON,

If you used the Korean GI Bill, that means you had to serve during the Korean Conflict, which was between June 1950 and July 1953.

At the end of the Korean War you were just 18 and were only old enough during the last year of that War, unless you enlisted at a younger age than 18.....
