The FE Electrical and Computer exam rewards fast pattern recognition. A circuit problem, power problem, signal problem, or digital logic problem usually gives away its path if you know what to look for. This guide gives you the topic map, the high-return study order, worked examples, and a 12-week plan that keeps your practice focused on the questions most likely to move your score.
FE Electrical Exam at a Glance
- 110 questions in 5 hours 20 minutes (computer-based, year-round)
- 17 topic areas — Circuit Analysis is the highest-weight single topic
- Big 4 topics (Circuits, Electronics, Signals, Digital) account for ~20–33% of the exam
- NCEES provides the FE Reference Handbook digitally — no outside notes allowed
- Most successful candidates study 200–300 hours over 8–16 weeks
What Is the FE Exam and Why Does It Matter?
NCEES administers the computer-based FE exam at Pearson VUE testing centers. You get 110 questions in 5 hours and 20 minutes, plus the digital FE Reference Handbook. Treat the handbook as part of your workflow: recognize the topic, jump to the right equation or table, then use the calculator cleanly enough that arithmetic does not steal the point.
Passing the FE exam earns you the designation of Engineer Intern (EI) or Engineer in Training (EIT), depending on your state. From there, after accumulating the required years of professional experience (typically four years under a licensed PE), you become eligible to sit for the PE exam and earn full licensure.
Career Benefits of Passing the FE Exam
- PE licensure pathway: A PE license is legally required to sign and seal engineering drawings, offer services directly to the public, and hold certain senior engineering positions.
- Competitive advantage: Even before you earn your PE, the EIT credential signals competence and commitment to employers.
- Higher earning potential: Licensed professional engineers consistently earn higher salaries than their unlicensed peers, with many surveys showing a 10–20% premium (Bureau of Labor Statistics).
- Career mobility: Licensure is recognized across all 50 U.S. states and territories through comity agreements, making it easier to work in different jurisdictions.
What Are the 17 Topic Areas on the FE Electrical Exam?
The FE Electrical and Computer Engineering exam draws from 17 distinct knowledge areas.

Where to Review the Highest-Return FE Electrical and Computer Topics
Use this map to turn the long topic list into a study path. Start with the handbook lanes you will use on exam day, then use the external refreshers only when a concept is weak enough to slow your practice.
Practice phasors, impedance, and three-phase work together.
Do not split circuits and power too far apart. AC circuit setup, complex arithmetic, real/reactive power, transformers, and three-phase relationships reinforce each other.
- Handbook move: mark the circuit, AC power, and conversion sections before timed sets.
- Practice move: write magnitudes, angles, and units explicitly to avoid calculator-mode mistakes.
Know the behavior before hunting for device equations.
Diodes, BJTs, MOSFETs, op-amps, filters, and small-signal assumptions reward pattern recognition. Start by predicting the operating region or ideal op-amp rule.
- Handbook move: group device models and op-amp relationships by circuit type.
- Practice move: annotate polarity and current direction before solving.
Turn logic questions into tables, states, or binary arithmetic.
Boolean algebra, logic gates, flip-flops, counters, number systems, memory, and computer architecture become easier when you force a structured representation.
- Handbook move: keep digital logic and computer-system references separate in your notes.
- Practice move: redraw state or truth tables even when the question feels simple.
Connect Laplace, transfer functions, and frequency response.
Signals and controls problems are often lookup-friendly if you know whether the task is transform, block-diagram algebra, stability, or Bode interpretation.
- Handbook move: learn where transforms, system response, and controls tables begin.
- Practice move: label input, output, and transfer function before simplifying.
Protect the shared-topic points that do not require EE depth.
Complex numbers, matrices, probability distributions, expected value, and engineering economics appear alongside technical topics. They are good recovery points on a hard exam.
- Handbook move: mark math identities, probability tables, and economic factors.
- Practice move: build calculator fluency for complex numbers and distributions.
Source note: topic names and question ranges should be checked against the current NCEES FE exam page. External resources are optional review aids and may include material outside the FE exam scope.

Which Topics Should You Prioritize?
Not all 17 topics carry equal weight. A strategic study plan focuses your limited time where it will earn the most points.
The Big Five (30–46 questions, ~27–42% of the exam)
- Digital Systems (9–14 questions) — highest question count and very learnable with practice
- Electronics (7–11 questions) — requires solid device-level understanding of diodes, transistors, and op-amps
- Mathematics (6–9 questions) — foundational topic that supports nearly every other area
- Circuit Analysis (8–12 questions) — the backbone of electrical engineering
- Power Systems (8–12 questions) — heavily tested and formula-driven
If you can consistently answer these five topic areas correctly, you are well on your way to passing.
After mastering those, move to the mid-weight topics: Control Systems, Linear Systems, Signal Processing, Communications, Electromagnetics, Engineering Economics, Properties of Electrical Materials, Computer Networks, and Software Engineering. These collectively represent another 35–40% of the exam. Many are formula-driven and very learnable in a focused study block.
Finally, review the lower-weight topics: Instrumentation, Computer Systems, and Engineering Sciences. While they carry fewer questions individually, together they still contribute to your overall score—and many of these are among the easiest to pick up quickly. Ethics and Engineering Economics in particular offer a strong return on a small time investment.
Worked Examples: One Problem from Each Big Five Topic
Here are five short worked examples—one from each of the highest-weight topic areas. Each problem is at the difficulty level of an actual FE Electrical exam item. Try solving each one before reading the solution.
Example 1 — Mathematics: Complex Number in Polar Form
Problem: Express the complex number Z = 8 + j6 in polar form.
Solution: Compute magnitude and angle.
|Z| = √(82 + 62) = √100 = 10
θ = arctan(6/8) = 36.87°
Z = 10∠36.87°
Why it matters: Nearly every AC circuit, control system, and signal processing problem requires fluent conversion between rectangular (a + jb) and polar (r∠θ) form. The TI-36X Pro can do this with one button press—make sure you know which one.
Example 2 — Circuit Analysis: AC Series RL Circuit
Problem: A sinusoidal source Vs = 120∠0° V at ω = 377 rad/s drives a series combination of R = 100 Ω and L = 0.5 H. What is the magnitude of the current?
Solution: Compute the inductive reactance, total impedance, then current.
XL = ωL = (377)(0.5) = 188.5 Ω
|Z| = √(R2 + XL2) = √(1002 + 188.52) ≈ 213.4 Ω
|I| = |Vs| / |Z| = 120 / 213.4 ≈ 0.562 A
Why it matters: Series impedance problems with phasors are the most common circuit-analysis item on the exam. Know the reactance formulas for L (XL = ωL) and C (XC = 1/ωC) cold.
Example 3 — Electronics: Inverting Op-Amp Gain
Problem: An ideal inverting op-amp has Rf = 100 kΩ and Rin = 10 kΩ. If Vin = 0.5 V, what is Vout?
Solution: For an ideal inverting amplifier, Vout = −(Rf/Rin) · Vin.
Vout = −(100 kΩ / 10 kΩ)(0.5 V)
Vout = −(10)(0.5) = −5 V
Why it matters: Ideal op-amp shortcuts (virtual short, infinite input impedance) turn what look like multi-element circuits into one-line formulas. Memorize the gain formulas for inverting, non-inverting, summing, and differential configurations.
Example 4 — Power Systems: Three-Phase Line Current
Problem: A balanced three-phase load draws 10 kW at 0.8 lagging power factor from a 480 V (line-to-line) source. What is the line current?
Solution: Use the three-phase power relationship P = √3 · VLL · IL · cosθ.
IL = P / (√3 · VLL · cosθ)
IL = 10,000 / (1.732 · 480 · 0.8) ≈ 15.0 A
Why it matters: The factor of √3 is the single most common slip on three-phase problems. Keep the line vs. phase convention straight and most power-systems items are plug-and-chug.
Example 5 — Digital Systems: Frequency Division
Problem: A 1 MHz clock drives a 4-bit binary counter. What is the output frequency at the most significant bit (Q3)?
Solution: An n-bit counter divides the clock by 2n.
fout = fclk / 24 = 1 MHz / 16
fout = 62.5 kHz
Why it matters: Binary counters and frequency dividers are a staple of Digital Systems questions. Remember: each additional flip-flop divides the frequency by 2 and adds one bit to the counter’s modulus.

How Should You Structure Your 12-Week Study Plan?
Most successful candidates spend 200–300 hours preparing over 8 to 16 weeks. Here is a suggested 12-week plan:
- Weeks 1–2: Take a diagnostic practice exam to identify your strengths and weaknesses. Review Mathematics, Probability and Statistics, and Engineering Economics.
- Weeks 3–4: Deep dive into Circuit Analysis (DC and AC) and Engineering Sciences. Practice solving circuits by hand until the methods feel automatic.
- Weeks 5–6: Study Electronics (diodes, transistors, op-amps) and Power Systems (three-phase, transformers, per-unit). Work through as many practice problems as possible.
- Weeks 7–8: Cover Digital Systems, Linear Systems, and Signal Processing. Practice Boolean simplification, Laplace transforms, and Fourier analysis.
- Weeks 9–10: Study Control Systems, Electromagnetics, and Communications. Focus on Bode plots, root locus, and modulation techniques.
- Weeks 11–12: Review Computer Networks, Computer Systems, Software Engineering, Ethics, and Properties of Electrical Materials. Take two or more full-length timed practice exams. Review every question you get wrong.
Study Tips for Exam Day Success
- Practice under timed conditions: You have roughly 2.9 minutes per question. Build your pacing instincts by taking full practice exams with a timer. If a problem is taking too long, flag it and move on—you can return to flagged questions later.
- Do not leave questions blank: There is no penalty for guessing. If you are stuck, eliminate what you can, choose an answer, flag it, and move on. An educated guess is always better than a blank response.
- Focus on units and reasonableness: Electrical engineering problems frequently involve unit conversions (mA to A, kV to V, dB conversions). Carry your units through every calculation to catch errors early.
What Study Materials Do You Need?
The right resources make a significant difference in your preparation. Here are the essentials:
- NCEES FE Reference Handbook — The exact reference you will use during the exam. Study with it daily so you know where every formula lives.
- TI-36X Pro Scientific Calculator — The most capable NCEES-approved calculator. Essential for matrix operations, complex numbers, and number base conversions on the ECE exam.

Only NCEES-approved calculators are allowed. The TI-36X Pro and Casio fx-115ES PLUS are the most popular choices. The TI-36X Pro is especially useful for its matrix operations and polynomial solver, which help with circuit analysis problems.
Is the FE Electrical exam hard?
The FE Electrical exam is challenging because it covers 17 topic areas spanning circuits, electronics, power, signals, controls, and computer engineering. However, with 200+ hours of structured study and consistent practice with the reference handbook, most prepared candidates pass on their first attempt.
Can I use the TI-36X Pro on the FE Electrical exam?
Yes. The TI-36X Pro is on the official NCEES approved calculator list and is especially well-suited for FE Electrical because of its complex-number (polar/rectangular) conversions, matrix determinants and inverses, polynomial root solver, and base conversions. For a detailed comparison with the Casio fx-115ES PLUS, see our FE exam calculator guide.
Should I take FE Electrical or FE Computer Engineering?
NCEES combines them into a single exam—the FE Electrical and Computer Engineering exam. There is no separate FE Computer exam. The 17 topic areas cover both disciplines (circuits, power, and electromagnetics on the EE side; digital systems, computer networks, computer systems, and software engineering on the CompE side).
What score do I need to pass the FE Electrical exam?
NCEES does not publish a fixed passing percentage. The exam is scored using a psychometric cut score set by a committee of licensed professional engineers, and results are reported as pass/fail only. Historically, candidates who can correctly answer around 70% of realistic practice problems tend to pass.
How many times can I retake the FE Electrical exam?
NCEES allows up to three attempts in any 12-month period with a minimum two-month wait between attempts. There is no lifetime cap. If you do not pass, use the NCEES diagnostic report to target your weakest topic areas during the next study cycle.
Is the FE Electrical exam worth it if I don’t plan to become a PE?
For most electrical engineers, yes. Passing earns you the Engineer Intern (EI) or Engineer in Training (EIT) designation, which many employers recognize as a signal of technical competence. It also keeps the PE path open for senior roles in power, utilities, or consulting where a PE license is often required. The FE is meaningfully easier to pass right after graduation than years later.
