Hello all.
I am a lowly mechanical engineer, studying for an equivalence exam through my employer (a regulated utility operator), to allow me to bid positions on the electric side of the house. I am currently a gas engineer.
I already failed my first attempt at the test, due in no small part to questions like this:
"Given an impedance function [Z=60<pi/3], determine the values of the parallel elements".
Now, I have no problem with vector math, or calculating total impedance from given values of R, C and L. But I think even a mechanical engineer can see that this problem is indeterminant. Am I right? Even if I assume a voltage, say 100V<0, I still have too many unknowns.
Isn't there an infinite number of possible combinations to result in any arbitrary total Z?
I apologize if this question seems beyond basic - but I've been wracking my brain trying to see a solution! Any help would be greatly appreciated.
