DK PE's explanation is correct as far as where the percentage belongs. Thanks. Josh

Wildsoldier, Yes, you are absolutely right. There needs to be some information there after the colon. Our next errata will include the appropriate information. It must have been frustrating to try to calculate a voltage out of thin air! Josh

Wildisoldier, You are correct. The question should have stated: "...if the transformer's HIGH-SIDE rated values" An errata for this question will be coming out via email on 9/28. The only alteration to the question will be adding "high-side" as indicated. I wanted to force you to do the...

Yes, snerts50 is correcnt. Errata have been issued for this via email. If you have not received it, please contact me. Josh

Errata for this has already sent out, please let me know if you have not received it. Please note that EEVA is working from an old version of our tests which have since been reorganized. Anyone who has purchased tests since July is working from the current-release question organization. Josh

Good catch, everybody! I've looked this over and I agree with everybody here. Errata for this question will be issued via email to all customers on 9/28. Josh

I don't believe this problem contains an error. As explained above, there are two ripple factor formulas. The difference in the two formulas is which Vrms are you going to use: the rms value of the AC supply components; or the rms value of the outputted rectified waveform. In this particular...

Ugh! Tell me about it with the shipping. We're getting killed on what we're being charged. Right now we take a $ hit on EVERY package we send, paying a portion of the shipping charge out of our pocket. I wish we could set the prices, but the shipping companies are are charging an arm and a...

All 4 of Complex Imaginary's practice tests are for the Power PE. So, yes, Complex Imaginary is "power-specific".

No apologies necessary. I know it's nothing personal, and I didn't consider it an attack at all. You had your concerns, and we talked about it. That's exactly what these forums are for. I call this a conversation: no animosity at all. I appreciate the interaction - seriously, thanks. I've...

Okay, I respect your concerns, so I will do my best to provide honest answers to your questions/objections: 1. Why didn't we lower the price when one, single person had said that he/she didn't like it? Because - honestly - I have to try to make a living. I left my job and incurred huge...

Certainly. Your order literally came in as I was creating the discount, so we just missed it by a minute. Check you email inbox, you should have gotten word from Paypal with the refund info. Take care Mahmoud, I hope the exam goes well for you. Josh

We understand that our material can seem expensive, especially as the economy is so rough right now. We genuinely try to make it as cost effective as possible, while still being able to remain in business. In order to offer our material at the absolute lowest cost, we've begun a promotion...

R2KBA, This is not an issue of using the MVA method versus the per-unit method. There is no real per-unit work to be done since no actual impedances were given, only the proportion of impedances to each other. This is done to make the problem easier to solve; they are basically giving you the...

We've continued to make free Youtube video tutorials for the engineering community studying for the Electrical PE. We have just finished our set on the Per-Unit Method. This often-misunderstood topic is presented in a simple and direct a way in these videos - I hope they help those studying...
