Electrical Diagrams and Schematics
Figure 10 provides an example of the relationship between a schematic diagram (Figure 10A) and
a wiring diagram (Figure 10B) for an air drying unit. A more complex example, the electrical
circuit of an automobile, is shown in wiring diagram format in Figure 11 and in schematic format
in Figure 12. Notice that the wiring diagram (Figure 11), uses both pictorial representations and
schematic symbols. The schematic (Figure 12) drops all pictorial representations and depicts the
electrical system only in symbols.
