Thanks Szar.  i really appreciate your efforts/responses

i didn't post my full solution with my question because i thought its primary calculations were wrong. why did they calculate it as if it were a WYE system then convert to delta?  That's why my angles don't match

A Delta-Delta transformer, 10:1, Primary side line V = 1732, Primary side line I = 17.3, 0.94 lagging PF, ABC phase sequence PRIMARY SIDE: VAB=VL=1732<0 PF angle = cos-1(.94) = -20 deg IL=17.3<(0-20)=17.3<-20 deg IAB=(IL/1.73)<(+30deg) = 10<(-20+30)=10<+10 deg Is what I...

Is Ibase incorrect here?  Shouldn't it be using 13.8kV instead of 1kV?

A 480VRMS AC single phase source is sent through a single phase half wave rectifier.  What is the average voltage at the output of the rectifier? Answer: Vmax = sqrt(2)*Vrms= 679 Vavg = (1/2pi) * integral of 679sin(theta) from 0 to pi = 216 V To me, when I see the solution, Vmax was chosen...

If there is an NEC question on sizing a circuit breaker, is it considered a code and standard question or a protection question; or both?

How similar have you found all of the exams you have taken?  Similar in difficulty and questions? I just took it for my first time and failed.  I did not have a lot of time to prepare and I have kids which made it even more difficult.  However, after reviewing all of the material and practice...

i really hope we don't have to wait until next week.   if this website wasn't booming with threads i probably would look or care only once or twice a day, now i'm looking every 5 mins

when one state finally posts results, and a lot of states usually do post on the first day, are they all at the same time?

If the cut score is 57, and say 4 questions were deemed void, a 53 would pass being scaled to a 57? If there are 4 void questions, does everyone get 4 pts added to their score?  What if you got all 4 right?  Doesn't matter? Also, Power seems to have a low pass rate usually of ~60%, and the cut...
