CHAPTER 1 · EASA Module 3.1
Electron Theory
The building blocks of aviation electricity — the composition of matter, the structure of the atom, electron shells and energy levels, and why materials behave as conductors, insulators or semiconductors.
CHAPTER 2 · EASA Module 3.2
Static Electricity and Conduction
How electrical charge behaves at rest — the build-up and distribution of electrostatic charges, the laws of attraction and repulsion, the units of charge and Coulomb’s Law, and how electricity is conducted through solids, liquids, gases and a vacuum.
CHAPTER 3 · EASA Module 3.3
Electrical Terminology
SI prefixes and conversion factors, conventional and electron current flow, electromotive force (voltage), current and the ampere, and how resistance links voltage and current.
CHAPTER 4 · EASA Module 3.4
Generation of Electricity
How electricity is produced — by friction, by pressure through the piezoelectric effect, by heat with thermocouples, by light in photovoltaic cells, by chemical action in cells and batteries, and by magnetism and motion in the generator.
CHAPTER 5 · EASA Module 3.5
DC Sources of Electricity
The DC sources that power an aircraft — primary and secondary cells, lead-acid and nickel-cadmium batteries, their ratings, testing and charging, plus thermocouples and photo-cells.
