This ringbound book provides a reproduction of a major U.S. Army Training Circular, TC 9-60, Communications Electronics Fundamentals, Basic Principles of AC/DC Alternating Current and Direct Current. This publication is a reference training circular for the electronics-engineering field. This publication provides background knowledge for the electronics technician. The technician is required to safely and efficiently operate and maintain electrical systems and apparatus. This TC reinforces good electrical practices and promotes the safe operation of the many electrical systems in the electronic shop. This publication covers the basics of direct current and alternating current. It introduces the physical properties of electricity and electromagnetism and describes how electricity is produced, stored, distributed, and used. This publication also identifies important safety practices to follow when working with electricity. Some of the contents include: Safety, Danger Signs of Equipment Malfunction, Electrical Shock, Fundamentals of Electricity, Nature of Charges, Magnetism, Energy and Work, Electric Current, Resistance, Conductance, Resistors, Wattage Rating, Direct Current, Ohm s Law, Batteries, Battery Charging, Concepts of Alternating Current, Sine Waves in Phase, Magnetic Fields, Inductance, Power Loss in an Inductor, Capacitance, Capacitors, Inductive Reactance, Impedance, Transformers, Core Characteristics, Effect of a Load, Taps, Windings, much more. Our news and educational titles are privately compiled collections of official public domain U.S. government files and documents - they are not produced by the federal government.
