A&P General: Ohm's law, power and series-parallel circuits
Electricity is the biggest General subject in this site's weighting, and most of its questions are short calculations. The distractors are predictable: the answer you get by multiplying instead of dividing, or by adding parallel resistances as if they were in series. Learn the handful of formulas below and the sanity checks that go with them.

Weight and balance questions on the General test are arithmetic dressed in terminology. If you can compute a moment, a loaded CG, the effect of removing equipment and a percent of MAC, and you know what tare, datum and basic empty weight mean, the subject is free points.

Corrosion identification and inspection (ACS code AM.I.G.K6) was the FAA's single most-missed General code from April 2024 to March 2025, missed 77% of the time. The questions turn on a few distinctions: where each form shows up, what it looks like, and which metal corrodes when two are coupled.

What a certificated mechanic may and may not do is the most testable rule set in the General, and 14 CFR 65.81 was amended in July 2025. Every fact below is checked against the current eCFR text, not an old question bank.
Drill it · 10 questionsMaintenance records, return to service and FAA Form 337
The General tests the exact contents of a maintenance entry, the difference between a 43.9 work entry and a 43.11 inspection entry, where Form 337 goes, and which records stay with the aircraft when it is sold.
Drill it · 8 questionsAircraft bolts, nuts, rivets and safety wire for the A&P General
Hardware questions reward memorized codes: what an AN part number means, what the head markings say, when a self-locking nut can be reused, and the safety wiring rules the FAA handbook spells out.
Drill it · 12 questionsAviation fuel identification, fueling safety and fire classes
Ground operations questions favor the rules that prevent the worst accidents on a ramp: putting the wrong fuel in an engine, a static spark at the filler neck, and the wrong extinguisher on a burning magnesium wheel.
Drill it · 8 questionsThe Dirty Dozen and maintenance human factors (A&P General)
Human factors questions are definitions taken almost word for word from chapter 14 of the FAA General handbook, often with the handbook's own examples. Learn the twelve factors and the few models around them and this subject becomes recognition, not reasoning.
