A circuit design (electrical diagram, elementary diagram( digital schematic) is a graphical representation of a electric circuit. A pictorial circuit structure utilizes straightforward images of elements, while a schematic diagram shows the components and interconnections of this circuit utilizing standardized symbolic representations. The demonstration of the interconnections between circuit components in the schematic diagram doesn't necessarily correspond to the physical arrangements in the final device.

Contrary to a block structure or layout diagram, a circuit diagram indicates the actual electrical connections. A drawing supposed to portray the physical arrangement of the cables as well as the components they join is known as art or layout, physical designor wiring diagram.

Once the schematic has been created, it's converted into a layout that can be fabricated onto a printed circuit board (PCB). Schematic-driven layout begins with the procedure for schematic capture. The outcome is known as a rat's nest. The rat's nest is a mess of wires (traces ) criss-crossing every other to their own destination nodes. These wires are routed either manually or automatically by the usage of electronic design automation (EDA) tools. The EDA tools organize and rearrange the positioning of elements and find avenues for paths to connect many nodes.

An ordinary, hybrid fashion of drawing combines the T-junction crossovers using"dot" connections along with the wire"jump" semi-circle logos for insulated crossings. This way a"dot" that is too small to view or that has unintentionally disappeared can still be clearly distinguished from a"jump".

In computer engineering, circuit diagrams are helpful when imagining expressions with Boolean algebra.

Circuit diagrams are utilized for the layout (circuit design), structure (such as PCB layout), and maintenance of electric and electronic equipment.

Teaching about the functioning of electric circuits is usually on primary and secondary school curricula. Usage of diagrammatic representations of circuit diagrams might aid understanding of fundamentals of power.

It's a usual although not universal convention that schematic drawings are organized on the page from left to right and top to bottom in exactly the same order as the flow of the most important signal or energy path. For example, a schematic for a wireless receiver may start with the antenna input in the base of the page and finish with the loudspeaker at the right. Positive power supply links for each point would be displayed towards the top of the page, with grounds, negative supplies, or other return paths towards the ground. Schematic drawings meant for maintenance might have the main signal paths highlighted to assist in comprehending the signal flow through the circuit. More complex apparatus have multi-page schematics and have to rely upon cross-reference symbols to demonstrate the flow of signals between the different sheets of the drawing.

Detailed rules for reference designations have been provided in the International standard IEC 61346.

The linkages between leads were simple crossings of traces. With the arrival of computerized drafting, the link of two intersecting cables was shown with a crossing of wires with a"dot" or"blob" to signal a link. At precisely the same time, the crossover has been simplified to be the same crossing, but with no"scatter". But , there was a danger of confusing the wires which were attached and not attached in this manner, if the dot was drawn too little or unintentionally omitted (e.g. that the"scatter" could disappear after several moves through a backup machine). [4] Therefore, the modern practice for symbolizing a 4-way cable link is to draw a direct cable then to draw another wires staggered together using"dots" as relations (see diagram), in order to form two distinct T-junctions that brook no confusion and therefore are clearly not a crossover.

Circuit diagrams are pictures with symbols which have differed from country to country and also have shifted over time, however, are now to a large extent internationally standardized. Simple components frequently had symbols intended to represent some characteristic of the physical structure of the device. As an example, the symbol for a resistor shown here dates back to the days when the component has been made by a very long piece of wire wrapped in this fashion as not to create inductance, which could have left it a coil. These wirewound resistors are currently used only in high tech software, smaller resistors being throw out of carbon composition (a mixture of carbon and filler) or manufactured as a insulating tubing or processor coated with a metallic film. The globally standardized symbol for a resistor is therefore now simplified into an oblong, occasionally with the value in ohms written inside, as opposed to the zig-zag logo. A less common symbol is merely a set peaks on a single side of this line representing the flow, instead of back-and-forth as shown here.

Wire Crossover Symbols for Circuit Diagrams. The CAD symbol for insulated crossing wires is the same as the elderly, non-CAD emblem for non-insulated crossing wires. To prevent confusion, the cable"leap" (semi-circle) logo for insulated wires from non-CAD schematics is advocated (rather than utilizing the CAD-style symbol for no link ), in order to avoid confusion with the first, older style emblem, meaning the exact opposite. The newer, advocated style for 4-way wire connections in both CAD and non-CAD schematics would be to stagger the joining cables into T-junctions.

Detailed rules for the preparation of circuit diagrams, and other document types used in electrotechnology, are supplied in the international standard IEC 61082-1.

Principles of the physics of both circuit diagrams are usually taught with the use of analogies, like comparing functioning of circuits to other closed systems like water heating systems together with pumps becoming the equal to batteries.

Relay logic line diagrams, also called ladder logic diagrams, use a different common standardized tradition for organizing schematic drawings, using a vertical power supply railing on the left and another on the right, along with elements strung between them like the rungs of a ladder.

On a circuit diagram, the symbols to elements are tagged with a descriptor or reference designator matching that on the listing of components. As an instance, C1 is the initial capacitor, L1 is the first inductor, Q1 is the first transistor, and R1 is the first resistor. Often the value or type of this part is given on the diagram beside the component, but detailed specifications could proceed on the parts list.

For crossing wires that are insulated from one another, a small semi-circle symbol is commonly utilised to display 1 cable"leaping over" another cable [3][7][8] (similar to the way jumper cables are utilized ).
