Study UnitUnderstanding andUsing ElectronicDiagramsByThomas GregoryIn your studies so far, you ve learned the basic principles ofhow electrical circuits provide power for useful work. Basiccircuits consist of a power source, components that regulatethe flow of current, and loads such as motors, lights, heat-ers, and more complex devices like computers or and Electronic technicians may work installing,servicing, maintaining, and troubleshooting hundreds of dif-ferent electrical and electromechanical devices from manydifferent manufacturers, on a regular basis. Over the years astandard visual language has evolved that allows designers,engineers, and technicians to effectively describe these elec-trical devices functions.
Schematic Diagrams Schematic diagrams document the connection points and construction methods of electrical and electronic circuits. Figure 1shows a simple schematic diagram of a power sup-ply; on it you can see some of the conventions used. Figure 2 shows the symbols for such basic components as wires and Understanding and Using Electronic ...
