Better luck next time Elastic. You have the right attitude. Have a drink and dust yourself off ready for the next round! :)

Creber - rofl.

Nevermind. CAPLS answered my question in earlier post: "License Lookup should be updated by Monday morning.". Thanks CAPLS!!! I can enjoy my weekend now. Was freaking me out that my name wasn't showing up.

If we passed how long before the dept. consumer affairs website is updated?

PASSED ELECTRICAL!!!

I really thought today was going to be the day...but looks like we're about to burn through another day given the time :(

Exam results/diagnostics not yet available. Look familiar?

Who else has an employer that keeps asking: "Have you got your results yet??" -- So frustrating not being able to specify when to stop them from asking!!

Yes, good luck to everyone! Thanks to all the contributors on this board. I'm now thinking more about the after test beverages then the exam itself :P

NCEES method works for me on both problems. Show us your working....

My understanding is if the system is UNGROUNDED then the neutral will shift if phase B is connected to ground, which is why the line to line voltage is unchanged. However, if we the system is GROUNDED at the source then you are tying ground to neutral i.e. the neutral is tied to 0V. So Vcb =...

I *think* Vbg would then be equal to the line to neutral voltage because the system would be grounded.

Agreed

Soma, In a 3 phase system, line to neutral voltages are always phase shifted by 30 degrees behind line to line voltages. The only reason they convert to Y configuration is because it's convienant. You could work with the phase to phase voltages but then you need to apply Kirchhoff's voltage...
