ASVAB Electronics Information: what it tests and how to study
Electronics Information is scored on the ASVAB but is not one of the four AFQT subtests. The official page describes it as testing knowledge of electricity and electronics.

What does Electronics Information cover?
Official description: “knowledge of electricity and electronics” (Official ASVAB: What to Expect (checked 2026-11-12)). Basic circuit ideas (voltage, current, resistance, series and parallel paths) are the usual starting point; the official site does not list topics, so treat this as study direction, not a syllabus.
AptiStep does not cover Electronics Information. The app and this website focus on the four subjects that make up the AFQT (Arithmetic Reasoning, Mathematics Knowledge, Word Knowledge and Paragraph Comprehension). This page is an explainer from official sources, not a practice set. For official Electronics Information examples use the Official ASVAB: Sample Questions.
How is Electronics Information tested on the CAT-ASVAB and on paper?
On the computer version the official table lists 15 scored questions and up to 15 unscored tryout questions, with a time limit of 10 minutes without tryout questions or 21 minutes with them. On paper it has 20 questions in 9 minutes. Source: Official ASVAB: What to Expect (checked 2026-11-12).
How do I study for Electronics Information?
Learn the three core quantities and how they relate. Worked example, not a test item: in a circuit with 12 volts across a 4 ohm resistor, current is voltage divided by resistance, 12 ÷ 4 = 3 amps (Ohm’s law, V = I × R). Then practice reading simple circuit diagrams and symbols.
Why does Electronics Information matter if it is not in the AFQT?
Electronics Information feeds the Electronics line score for some jobs (reported by Military.com for the Air Force, checked 2026-11-12). It matters only if your target job lists it.
See ASVAB line scores and the AFQT explainer for how subtests combine.
