I just got a response from the administrator of the test in Maryland, who said that the "no pencil mark" rule used to be the case, up through the last exam this past October. But that rule now no longer applies.

I've seen posts that say reference material taken into the exam can't have pencil marks, but I can't find anything that actually says this. Is it perhaps a state-by-state issue?

I'm putting together an email list of those studying for the April Power exam. My thinking is that this would be a quick way to get an answer for something that has you stumped, rather than waiting for people to check this forum. As for an actual study forum, I'm already signed up for the...

I see an apparent conflict between Wildi and the NCEES practice exam that I'd like help rectifying (no pun intended). Wildi p. 494 says that the peak inverse voltage across a diode is equal to the peak value of the AC line voltage, or 1.414*Vrms. The NCEES practice exam #515 says the minimum...

I may be interested in an online group as well.

I understand the concept of the generated voltage, voltage drop within the machine, and the resulting line voltage. I just don't understand why the PF angle given for the current is given with respect to the generated voltage, and not the line voltage.

For this particular CI problem, why is it a given that the PF describes the relationship between the current and the GENERATED voltage as opposed to the LINE voltage?

Sorry, yes, the imaginary component is what I was referring to.

I'm taking the exam for the first time in April, so this is my ramping up time :) Is it correct to say that current and impedance have opposite polarities, so the current to a capacitive load has a positive angle with respect to voltage, and the impedance is negative?

iahim, are you sure about your last statement? My understanding is that a leading power factor (capacitive) has a positive power factor angle when expressed in polar form, and a positive imaginary component when expressed in rectangular form.
