A circuit diagram is a graphical representation of an electrical circuit. A schematic circuit diagram shows the exact components and interconnections of a circuit, whereas a pictorial circuit diagram uses simple images of the components. In either case, the purpose of the circuit diagram is to facilitate understanding and repair. In many cases, a schematic circuit diagram is necessary, especially for a first-timer or someone with no technical background.

Difference Between Pictorial and Schematic Diagrams

There are several ways to create a circuit diagram, including using a tool that is specifically made for this purpose. One option is to save circuit diagrams in a Word or PowerPoint file format, or as an Excel sheet. Once you save a circuit diagram, you can easily share it to others. Another option is to create an electronic circuit diagram drawer using a free online circuit diagram creator.

Another option is to download the free CircuitLab program and use it to create your own circuit diagrams. This application includes a large library of shapes and an interface similar to MS Office. It can be used for professional or educational purposes, and it allows you to create circuit diagrams and schematics in various formats. However, this program only runs online. You can download it from a popular website.

A circuit diagram is used to identify the elements of a system. The first step is to identify the devices in the circuit. These devices are usually very complex and have multi-page schematics. Those involved with designing these systems will need to use cross-reference symbols, which show the flow of signals between the sheets.
