What is the difference between schematic and circuit diagram

A plan, drawing, sketch or outline to show how something works, or show the relationships between the parts of a whole. A functor from an index category to another category. The objects and morphisms of the index category need not have any internal substance, but rather merely outline the connective structure of at least some part of the diagram's codomain. If the index category is J and the codomain is C, then the diagram is said to be "of type J in C".

This diagrams uses symbols to identify components and interconnecting lines to display the electrical continuity of a circuit. Ladder diagrams show how a circuit works logically and electrically. Wiring diagrams , also called connection diagrams, however, do show how equipment is laid out and the connections between them. A wiring diagram shows the relative layout of the components and the wire connections between them. Electronic schematics consist of digital electronic symbols that represent each of the components used.

On the following microelectronic device schematic diagram, the symbols are connected with lines that show you how to connect the components. The schematic diagrams are also used in many other fields, not just in electrical systems. For example, when you take the subway, the subway map for passengers is a kind of schematic, and it represents subway stations with dots.

The chemical process can also be displayed in a schematic diagram with symbols of chemical equipment. A circuit diagram also named electrical diagram, elementary diagram, and electronic schematic is a graphical representation of an electrical circuit.

Circuit diagrams are widely used for circuit design, construction, and maintenance of electrical and electronic equipment. Circuit diagrams can be divided into two categories - pictorial circuit diagram and schematic circuit diagram. Pictorial diagrams are much easier to understand than schematic circuit diagrams. By connecting realistic electrical components with the wiring, a pictorial diagram makes it easy and quick for viewers to identify the electrical components of a system immediately without professional knowledge required.

The below table shows the SI units that are generally used on schematic diagrams. In a schematic diagram , lines are used to represent wires, and symbols are used to represent components. The schematic diagram does not show the practical connection between the components or their position. It contains only symbols and lines. A wiring diagram is a generalized pictorial representation of an electrical circuit.

The components are represented using simplified shapes in wiring diagrams. Wiring diagrams generally give detailed information about the relative location and arrangement of devices.

To understand a PCB schematic, it is essential for us to learn how the components on the schematic are connected. It contains information about various components and the operating conditions of the circuit. Schematic nets define how components are interconnected in a circuit. The line between the two interconnected components is called a net.

A junction is formed when two or more wires intersect at a point. This junction is represented by placing a little dot node on the point of intersection as shown in the below image. Representation of nodes in a schematic diagram.

Nodes help us to identify the connection among the wires intersecting a point. The absence of a node at a junction means two separate wires are just passing by without any electrical connection. In order to make the schematic diagram more legible, the nets are labeled with their names, rather than drawing lines to show the connectivity.

The image below shows an example of a schematic diagram in which nets are labeled with their names.
