Study for FE

Just a reminder that my free live training on Phasor Diagrams and Impedance in 3-Phase Systems is coming up this week.

This is a topic that appears on both the FE Electrical & Computer and PE Power exams, and I’ll be covering the exact concepts you need to know, from phasor basics to delta and wye systems, line vs. phase quantities, and common problem-solving mistakes.

Study for FE

I’m excited to invite you to my free live training on Phasor Diagrams and Impedance in 3-Phase Systems.

This is one of the most important topics for both the FE Electrical & Computer and PE Power exams, and it can feel intimidating if you haven’t built a strong foundation yet. In this session, I’ll simplify it from the ground up and show you how to approach phasor and impedance problems with confidence.

We’ll cover:
  • Phasor fundamentals.
  • Constructing and interpreting phasor diagrams.
  • Impedance in AC circuits.
  • Balanced 3-phase systems.
  • Line vs. phase quantities.
  • Delta and wye connections.
  • Common exam mistakes.

Quick question for power engineers:

Your facility is consuming 100kW of real power.
Power factor: 0.70.

Your neighbor's facility is also consuming 100kW.
Power factor: 1.0.

Who does the utility prefer to serve?

The neighbor. Every time.

Here's why:

With PF 0.70, the utility needs to push more current through the lines to deliver the same 100kW to you.
More current = bigger conductors + bigger transformer + higher losses.

The utility is paying for all of that infrastructure.
You're only getting billed for the real power.

That's why utilities penalise poor power factor.
That's why power factor correction saves money.
And that's why this topic shows up on both the FE Electrical and PE Power exams.

Going from 0.90 to a unity power factor alone can reduce line losses by up to 19%.

New video on exactly how this works.

Three-phase circuit. Delta load. Now what?

You cannot apply Ohm's law directly to a delta load.
You need Y-Y — source in Y, load in Y.

The fix is delta-to-Y load transformation.

Balanced (all three phases equal):
Z_Y = Z_Δ / 3
No phase angle change. Just divide by three.

Example: 9Ω delta → 3Ω wye per phase ✅
Example: (9+3j)Ω delta → (3+j)Ω wye ✅

The key rule: line voltage and line current are not affected by the transformation. That's what makes it valid.

Unbalanced load? That's where:
Z1 = (Za × Zc) / (Za + Zb + Zc)
Z2 = (Za × Zb) / (Za + Zb + Zc)
Z3 = (Zb × Zc) / (Za + Zb + Zc)

Full session covering both cases is now live.

Study for FE

One of the most common reasons engineers don't pass the FE or PE Power exam on their first attempt has nothing to do with the technical content.

They burn out before exam day.

Three things that prevent it:

1️⃣ Cap your topics — no more than 1 to 2 new topics per week. Covering too much at once builds pressure, not momentum.

2️⃣ Take one full day off — your brain consolidates during rest, not during the tenth hour of studying on a Sunday.

3️⃣ Same time. Same place. Every session. You stop fighting the habit and start running on autopilot. (This one is straight from Atomic Habits — it works.)

Short video on all three is now live.

Which of these do you struggle with most?

Quick question for engineers preparing for the FE exam:

$10,000 loaned to a friend at 10% per year.

After 40 years, how much do they owe you?

Simple interest: $50,000
Compound interest: $452,593

Same loan. Same rate. Same time period.
One formula. One exponent. A difference of over $400,000.

This is why compound interest has been called the eighth wonder of the world.
(The Einstein attribution is disputed — Wasim covers that too.)

And this is also why the interest rate is the most important input in every Engineering Economics calculation on the FE exam.
Get it wrong before you start calculating, and everything downstream is wrong.

New video on simple vs compound interest is now live.

Drop a comment: Were you taught compound interest in school, or did you have to figure this out on your own?

Study for FE

Sohini got her PE Power exam results on a Wednesday.

She hadn't passed.

She had given up weekends. Social life. Everything.
Work, come home, study. For six months.

She emailed Wasim the same day.
They had a call the same day.

Wasim reviewed her diagnostic report and told her:
"You were almost there. One quick round of review and you'll be fine."

Four weeks later, she sat the exam again.

She passed.

And here is what she said:

"I have earned this. It was not luck.
I really know my material."

FE Electrical: October 2023 ✅
PE Power first attempt: September 2024 ✗
PE Power second attempt: October 2024 ✅

13 months. One family emergency. One setback.
Zero quit.

If you are in a repeat situation right now, this one is for you.

Study for FE

The Engineering Economics section on the FE exam includes three different interest rates.

Most candidates are familiar with the nominal interest rate.
But the exam will give you a compounding frequency — and that changes everything.

Here's the decision rule Wasim uses:

📌 Compounding once per year → use nominal rate R directly
📌 Transactions happening monthly, compounding monthly → use interest rate per period: i = R/m
📌 Compounding monthly, transactions annually → use effective interest rate: i_e = (1 + R/m)^m − 1

Example: 6% nominal, compounded monthly
→ i = 6/12 = 0.5% per month
→ i_e = (1.005)^12 − 1 ≈ 6.168% per year

Both give the same financial outcome, but the wrong choice in the wrong scenario
will give you the wrong answer before you've done a single calculation.

Study for FE

The FE Electrical exam has 17 sections.

But 5 of them account for approximately half of the entire exam.

Here they are:

1️⃣ Mathematics — ~10%
2️⃣ Circuit Analysis — ~10%
3️⃣ Electronics — ~10%
4️⃣ Power Systems — ~10%
5️⃣ Digital Systems — ~10%

Wasim's verdict on the most important single section?

Circuit Analysis. Without hesitation.

Not because it's the hardest — but because it's deceptive.
The tools are simple: Ohm's law, Kirchhoff's laws.
But the mistakes are almost always conceptual, not arithmetic.
And on the actual exam, those conceptual gaps cost you points you can't recover.

His verdict on the hardest section?

Digital Systems — especially for power engineers who never touch
flip flops, counters, or Boolean logic in their day job.

Full breakdown in the new video.

Which of these five are you most confident in right now?

24 hours to go! ⚡

My Norton’s Theorem webinar is happening tomorrow at 10:00 PM ET, and I’m excited to break it down in a way that actually makes sense for FE Electrical & Computer and PE Power prep.

If Norton’s Theorem has ever felt slow, confusing, or easy to forget under pressure, this session is for you. I’ll walk through the core ideas, the Norton–Thevenin relationship, and how to apply it quickly on exam-style problems.

Here’s what I’ll cover:

What Norton’s Theorem is and when to use it.

How to find Norton current and Norton resistance.

Norton vs. Thevenin equivalents.

Circuit simplification techniques.
