The primary goal of this Electrical Schematic Diagram is to highlight circuit elements and how their functions interact with one another. Schematics is a useful troubleshooting tool because they show which components are in series or parallel and how they are connected. Resistors, capacitors, inductors, diodes, logic gates, fuse contacts, switches, and other components are frequently seen on schematic diagrams. Every element in a circuit diagram is represented by its symbol. Electrical Schematic Diagrams should be organized for simplicity and ease of understanding, with no regard for the actual physical location of any component, instead of focusing on how they connect.
