200 reference questions on the electrical engineering behind airfield ground lighting: Ohm's law and series-circuit calculations, AC fundamentals, transformers, earthing, insulation resistance, cable calculations, protection, relays, contactors and electrical safety for maintenance personnel.
Every question sits in one of ten electrical topics, from Ohm's law and AC fundamentals through transformers, earthing, insulation resistance and cable calculations to protection, relays, contactors and electrical safety. The bank mixes definitions with worked numerical problems and AGL-specific scenarios, so you practise the arithmetic and the reasoning behind it.

Short answers about the electrical engineering question bank, how the drill and scoring work, and the topics it covers.
It is a 200-question reference and drill on the electrical engineering an AGL engineer relies on: Ohm's law, AC fundamentals, transformers, earthing, insulation resistance, cable calculations, protection, relays, contactors and electrical safety. Every question has a model answer, an explanation, key terms and references.
Ten topics: Ohm's Law (20), AC Fundamentals (25), Transformers (25), Earthing (20), Insulation Resistance (20), Cable Calculations (25), Protection (20), Relays (15), Contactors (15), Electrical Safety (15).
Four levels: Beginner (58), Intermediate (81), Advanced (54) and Expert (7). Beginner questions cover definitions and purpose, while Advanced and Expert questions add multi-step calculations and practical AGL scenarios.
Technical explanation (102), numerical (41), practical scenario (19), procedure (8), AGL-specific (8), troubleshooting (6) and safety (4), plus a handful of test, inspection, interpretation and standards-reference questions.
Drill Mode gives a shuffled run through the bank, filtered by level and topic if you choose. Type your own answer and check it, or just reveal the model answer. Typed answers are scored locally in your browser by weighted key-term matching with stemming and typo tolerance, plus overall wording overlap. It is a close approximation, not true AI grading, and for numerical questions you should always compare your working with the model answer.
Yes. About 41 questions are numerical, covering voltage drop, series and parallel resistance, power relationships (P = VI, I²R and V²/R), and cable resistance and voltage-drop problems set in simplified AGL circuits. Each shows the answer and the reasoning behind it.
Ohm's law links voltage, current and resistance, and the power relationships built on it let you check load, cable loss and the voltage reaching a device. The Ohm's Law topic (20 questions) builds from definitions up to integrated AGL circuit problems.
Earthing (20 questions) covers why a controlled connection to earth keeps exposed conductive parts at a safer potential and gives fault current an intended path. Insulation Resistance (20 questions) covers what the measurement means, how it is tested and how readings are interpreted.
Yes. Protection (20) covers how overloads, short circuits, open circuits and faults are detected and cleared, Relays (15) covers coil-and-contact switching devices, and Contactors (15) covers switching devices designed to make and break power circuits repeatedly.
Fifteen questions on hazards AGL maintenance personnel must consider before starting work, including electric shock, arc flash, unexpected energisation, backfeed or induced voltage, stored energy, defective insulation and unsafe grounding. It supports, but does not replace, your site procedures and permit-to-work rules.
Many answers are grounded in general electrical engineering principles (91 questions), alongside FAA AC 150/5340-26C (59), FAA AC 150/5370-10H (44), FAA AC 150/5340-30J (26) and FAA AC 150/5345-47C (19). Protection, contactor and cable questions also cite NFPA 70E (10) and NFPA 70 (9).
Yes. Interviewers often start with electrical basics before moving to AGL systems. The 41 numerical and 19 practical-scenario questions help you practise showing your working aloud, and the 7 expert questions mirror harder design and diagnosis discussions.
