PE Exam Question: Short circuit study and X/R

[steve66]

Thank you for the long explanation. I'll need to chew on it for a while tonight before it makes sense to me, but all the info I need is given.

I swear I don't feel smart enough to be an engineer. If egr doesn't work out then I'll be a drafter lol.

I've been an engineer for longer than I care to mention, and I'm still not sure that answer is even right. Most people use software to do short circuit calculations, so once the test is passed, we tend to fall out of practice with doing this stuff by hand.

At any rate, not giving one impedance and simply stating the X/R ratios are equal provides a extra layer of difficulty. I'll bet you won't find many if any questions like that on the exam.

I'll bet you won't find many if any questions like that on the exam.

In the old days where you had to actually put pencil to paper and work a problem and show your work including assumptions; I could see this being on the test. But these days with everything being multiple choice, I agree, probably not likely.
