Electricity runs a great deal of all modern devices. Like any other means of transportation, aircraft rely on electricity for a number of functions, including, but not limited to, lighting, communication, navigation, and environmental control. In fact, some newer aircraft designs eliminate control cables and rely entirely on electrically actuated flight controls. As an aircraft maintenance technician, you will encounter electricity every day, and a solid grasp of this subject is essential.
This section addresses the fundamental concepts that are the building blocks for advanced electrical knowledge and practical troubleshooting. Some of the questions addressed are: How does energy travel through a copper wire and through space? What is electric current, electromotive force, and what makes a landing light turn on or a hydraulic pump motor run? Each of these questions requires an understanding of many basic principles. By adding one basic idea on top of other basic ideas, it becomes possible to answer most of the interesting and practical questions about electricity or electronics.
Our understanding of electrical current must begin with the nature of matter. All matter is composed of molecules. All molecules are made up of atoms, which are themselves made up of electrons, protons, and neutrons.
