Original public teaching example · PE Architectural Engineering
One question. The reasoning behind it.
A balanced three-phase load draws 75 A at a line-to-line voltage of 208 V and a power factor of 0.80. Which pair correctly gives its apparent power and real power?
View the answer choices
- A. 15.6 kVA and 12.5 kW
- B. 33.8 kVA and 27.0 kW
- C. 27.0 kVA and 21.6 kW
- D. 27.0 kVA and 27.0 kW
Compare the answer and reasoning
27.0 kVA and 21.6 kW
For a balanced three-phase load, use line-to-line voltage with the square-root-of-three factor. Apparent power is approximately 27.0 kVA; real power is apparent power multiplied by the stated 0.80 power factor, approximately 21.6 kW. This is a power calculation, not a complete conductor or protective-device selection.
What to practice next: Keep phase, line-to-line voltage and apparent versus real power separate.
Apply it to a different condition
A different balanced three-phase load draws 50 A at 480 V line-to-line with power factor 0.90. Find apparent and real power.
Check the new reasoning
Apparent power is √3 × 480 × 50 / 1,000 ≈ 41.6 kVA. Real power is 41.6 × 0.90 ≈ 37.4 kW. The power factor converts apparent to real power; it is not applied twice.
Teaching demonstration, not a candidate result or pass prediction. These examples are separate from protected assessments.
Try the interactive PE Architectural Engineering preview →One question, visible reasoning
A transformer question should teach more than the number.
A 30 kVA three-phase transformer is supplied at 480 V. The free sampler asks for its approximate full-load primary line current, using this original system exhibit.
Governing relationship
Line current = 30,000 ÷ (√3 × 480) = 36.1 A.
Why 62.5 A fails: Dividing by 480 alone omits the √3 factor for a balanced three-phase load. Another option uses the secondary voltage instead of the primary.
Every option in the eight-question sampler receives this kind of review. The sampler does not predict your exam result.

Four domains. One integrated building.
The official ranges describe the exam. The study allocation below is a starting recommendation from ReasonSpan™ and adapts after the baseline. These percentages allocate study time, not exam questions. Electrical receives additional calculation practice in this starting plan; use your baseline to increase Mechanical or any other area that needs more work.

Review course access- 01Diagnose
Measure accuracy by domain and record confidence before seeing explanations.

Included study tools
A complete preparation system, not a question dump.
Each tool has a distinct learning job and connects performance evidence to the next useful action while keeping the official handbook and standards visible.
Diagnostic evidence
A 40-question original baseline records early accuracy and confidence signals across all four domains before explanations are shown.
Focused lessons
All 18 modules include decision rules, governing relationships, a worked example, common errors, and reference paths.
Decision Cards
Ten balanced retrieval sets build fast recognition across the four domains, with option-by-option feedback and a spaced due queue.
Applied practice
A separate 144-question bank builds sets of up to 12 unseen questions by domain, module, or mixed coverage. Twelve additional drills cover multiple response, numeric entry, and matching.
Reference selection
Plan which reference and governing relationship to use with focused selection drills. These are not searches within an embedded handbook.
Full-length simulation
Two 85-question forms include single-answer, multiple-response, numeric-entry, and matching items, plus timed sections, a scheduled break, flags, and worked review.
Readiness evidence
The dashboard combines baseline, lesson, application, and mock evidence into next-action recommendations, not a pass prediction.
Account progress
Answers, ratings, flags, timers, and completion data sync to the candidate account so work can resume across study sessions.
How the program uses exam references
Reference discipline
Current rules first. Supporting books second.
The governing hierarchy is the October 2026 specification, PE Architectural Engineering Reference Handbook v2.1, and the exact editions of the listed codes and standards. Textbooks support explanation; they do not override the supplied exam references.
ReasonSpan™ does not distribute the NCEES handbook or third-party standards. Questions, diagrams, and explanations are original and are written to teach the engineering decision rather than reproduce protected exam material.

Program Q&A
Your PE Architectural Engineering questions, answered.
What does this program cover?
PE Architectural Engineering preparation across electrical, mechanical, structural and project administration decisions. It includes a 40-question baseline, 18 modules, 130 Decision Cards, 144 applied problems, reference drills and two separate 85-question mock exams.
How long does access last?
90 days of access from purchase. The current price is $129 as a one-time payment, with no automatic renewal. Review the cohort dates before buying, especially if your exam falls in a later year.
Is PE Architectural Engineering the same as the ARE?
No. PE Architectural Engineering is an NCEES engineering examination. The Architect Registration Examination is administered by NCARB. Choose the program for the examination you plan to take.
How does targeted review work?
Use the baseline to identify which systems, calculations or reference decisions need attention. Study the relevant modules, apply the method in new problems and use the two mock forms to rehearse sustained timing.
Is this an NCEES course?
No. ReasonSpan™ is independent, and its questions, figures and explanations are independently authored. Consult NCEES for official requirements and examination references.
Can I try the program before paying?
Eight free original questions and a complete worked lesson let you inspect the reasoning and teaching approach without an account or payment.
