AC43.13 1B & 2A covers which topic?

AC43.13 1B & 2A covers which topic?

• A. Basic terms associated with Direct Current in electrical systems
• B. The Avionics Certification Test Study Guide
• C. Electron
• D. E.M.F.

Answer: (A)

The main concept being tested is recognizing the scope of AC 43.13-1B and 2A, which focuses on basic electrical terminology used in DC circuits within aircraft systems. These advisory circulars cover the acceptable methods for maintaining and repairing electrical systems, and a solid grasp of DC terms—like voltage, current, resistance, Ohm’s law, and related concepts—is essential to apply those methods correctly. Because aircraft power distribution relies heavily on direct current from batteries and DC buses, understanding these basic terms is the foundation for any maintenance work described in those guides. That’s why the best answer is the basic terms associated with Direct Current in electrical systems. The other options refer to resources or concepts not describing the overall topic covered by those advisories: they’re not the subject of the guidance, and elements like electrons or EMF are parts of the broader DC electrical knowledge but not the overarching topic itself.
