Circuit diagrams are above all important for maintenance, error detection and circuit testing purposes. They contain all the details of a circuit with all its connections and individual components. With circuit diagrams it is possible to see how devices and systems are functioning.
Circuit diagrams have a particular characteristic: With a special horizontal, vertical as well as crossing free representation of current paths one wants to achieve that diagrams can be read as fast and easily as possible.
