An electrical schematic is a logical representation of the physical connections and layout of an electric circuit. Figure 7 Common Electrical Component Symbols. The diagram may be mailed or e-mailed. The message in the name determines the type of component, every component's name on an electrical schematic should be unique. 1. The schematic (Figure 12) drops all pictorial representations and depicts the electrical system only in symbols. Two very old three-way switches. These electrical schematic symbols will help you to identify parts when working with an electrical schematic. For schematic components like resistors, capacitors, and inductors, the value tells us how many ohms or farads they have. Notice that the wiring diagram (Figure 11), uses both pictorial representations and schematic symbols. If at a given instant the current is flowing into the transformer at the dotted end of the primary coil, it will be flowing out of the transformer at the dotted end of the secondary coil. This article concentrates on how electrical components are represented on diagrams and schematics. Electrical Symbols & Electronic Symbols. Undoubtedly, there are many electrical schematic symbols not mentioned on this list. A well documented schematic outlines the functionality of an electric circuit and provides the basis for assembly and troubleshooting of a system. 2. Analyzing Different Circuit Connections Look for components connected by straight or vertical lines. The symbols represent electrical and electronic components.
