About this module
EASA Part 66 Module 3 is one of the largest basic modules: eighteen sub-topics running from electron theory and Ohm's law through batteries, capacitance, magnetism and inductance to DC machines, AC theory, transformers, filters and three-phase generators and motors. Expect plenty of circuit calculations — series/parallel resistance, RC time constants, transformer ratios, power factor — alongside conceptual questions on generator and motor behaviour.
Electrical Fundamentals is essential for both B1 and B2 candidates, and it is the platform that Modules 4, 5, 13 and 14 stand on. Our bank mirrors the exam's favourite themes (Wheatstone bridges, back-EMF, star vs delta, hysteresis) and every answer carries a short explanation, so you build the intuition rather than memorising letters.
