A circuit diagram, known also as an electrical diagram or an electronic schematic, graphically represents an electrical circuit. A circuit is a pathway, connecting a group of electric or electronic devices with conductors. The diagram in electrical systems and components show a map of the path and the return of electrical circuits. Pictorial maps, common for the layman's use, display simple and recognizable images, such as a broken line for a switch or straight line for a wire. Schematic maps, often used by more advanced professionals, display the more complex industry standard symbols depicting amperes or terminals or other electric components.
With the increase of electronics in typical everyday items such as coffeemakers, vehicles, dishwashers, these diagrams have become a type of instructional tool and resource for repairing electronic devices. The diagram illustrates the path of electrical continuity. While it can appear complicated with its vast use of symbols, this diagram is simply a map displaying the path and connections of a circular route of electricity — the circuit.
