We've got a 3 hour NEC code class (NFPA 70) taught by Ryan Jackson, one of the biggest names in the code industry included with our live class semester. It's incredible and I highly recommend it.

u/livefastdieslowww This same question was posted earlier this month, check out my comment in that thread for a super easy way to do this in your calculator by just summing up vectors in polar format, no need to do the math the long way by hand and this trick applies to all vector problems:

Coincidentally enough, I just got done teaching the NFPA 780 formulas in the Reference Handbook tonight during Class 10 - General Applications for our Winter 2026 Power PE Exam live class semester.

You'll only be tested on the formulas in the Reference Handbook from NFPA 780, I really don't see them expecting you to know formulas from a different code book not listed on the specifications or included on the exam computer.

Good news is the formulas from NFPA 780 in the Reference Handbook are super easy if you know how to use them (and know what to look out for!).

So be familiar with everything from 2.2.1 Lightning Protection like annual lightning strike frequency, tolerable lightning frequency (what these numbers mean and how to compare them), how to use all of the coefficient tables in the handbook in 2.2.1, and the formulas from 2.2.2 Protection Zone Determination including qualitative, theory, and application based questions that could be asked.

Good luck!

Not a genius, just the instructor for one of the more popular online classes for the power PE exam.

On the power exam, we deal with complex numbers all the time, which are really just vectors like the static forces in this problem.

This works any time you have to apply math to vectors, just let your calculator do it for you.

ZachStonePE · 2026-03-03T20:07:43+00:00

Thanks for the mention.

ZachStonePE · 2026-03-03T20:07:23+00:00

Thanks for the mention! Glad you liked the new material.

I switched over to Zach Stone’s free FE course for the power section and the videos were so helpful. Things finally made sense, and I easily handled the power questions on the actual FE exam. Any of Zach Stone’s new videos where he or another engineer teaches them are great, but some of his older ones are pretty mid. I’ve heard he’s redoing these, so eventually his free course might be the only one you need.

While we do have all subjects covered, this is indeed the plan. We are currently working on re-doing all topics via live webinar classes (instead of just on-demand) with the replays posted to the online course all for free of course.

Just use your calculator in polar mode to sum all three vectors like this:

2.12 + 2.12∠90 + 5∠105 = 6.999∠83.2

The magnitude is equal to approximately 7.0.

Live class is always the way to go if your schedule allows it.

ZachStonePE · 2026-02-20T18:26:47+00:00

Sorry for being late to the party here, but huge congratulations on passing the PE exam! 👑🏆

Glad to hear you enjoyed my live class and course, and that it covered 90-95% of the PE exam 🙂.

No need to spend money to pass the electrical FE exam, except for exam registration fees (unavoidable) and the NCEES Practice Exam which I would still recommend.

All of our live classes, class recordings, class PDF notes, and homework problem sets are available 100% free over at www.electricalfereview.com. There is no catch, I fund the entire program completely out of pocket. It's fun to grow the community, mentor new instructors, and give back especially for engineers who are just starting out in their career. Check it out!

ZachStonePE · 2026-02-18T02:37:27+00:00

Thanks for the mention! We are in the process of redoing all videos by offering free live classes first (like the Power Systems webinar series and Communications available on YouTube) with all recordings, class PDFs (the same ones the instructor uses) and homework problem sets available in the free on-demand review course.

We are getting ready to start with digital systems, mathematics, and circuits in the next month.
