Divided into three sections, the book includes the complete syllabus for Electrotechnology Officers as specified by the Association of Marine Electronic and Radio Colleges (AMERC), with each section providing a series of questions and answers that will give the student practice at working at the examination level.The book introduces basic electronics, physical concepts of atoms and how electricity flows, conductors, insulators. It also introduces resistors, semiconductors, capacitor inductors and tuned circuits.The book explores the theory of how a range of navigational aids and radio systems work, how to operate and test them, and how to fault find to component or sub system level. Additionally, it includes theory of how radio communications systems work, how to operate them, and how to fault find to component or subsystem level.Importantly, this is the first textbook to be aimed primarily at ETOs, covering the changes to the STCW 2010. An essential buy.
