Electrical circuit
A circuit or wiring diagram is a visual display of an electrical circuit. Electrical and electronic circuits can be complicated. Making a drawing of the connections to all the component parts in the circuit's load makes it easier to understand how circuit components are connected. Drawings for electronic circuits are called "circuit diagrams". Drawings for electrical circuits are called "wiring diagrams". Like other diagrams, these diagrams are usually drawn by draftsmen, and then printed. Diagrams may also be created digitally using specialised software.
