What Is Meant By Schematic

By | March 31, 2023



If you are taking a course in electrical engineering, reading through a technical manual on the inner workings of an appliance, working with circuitry, or designing a product, you have probably heard the term schematic. But what is a schematic, and how can it help you in your work?

A schematic is a visual diagram that is used to represent a system, device, or circuit. In essence, it is a “map” of all the various connection points, allowing individuals to better understand the way an electronic device or system works. A skilled engineer will be able to quickly assess the flow of energy and information by studying a schematic.

The first use of a schematic diagram dates back to the 17th century, when English scientists Robert Hooke and Christopher Wren used them to describe their ideas for designs, such as bridges and buildings. Soon after, engineers were using them for the development of electrical devices.

Modern schematics are typically made up of symbols and lines that show the relationship between the components of an electronic device. Once the schematic is drawn, it can be used to test whether the device functions correctly and serves its purpose. It also helps greatly with troubleshooting, as it reveals any errors that have been made in the connections and allows the engineer to pinpoint where the fault lies.

Using schematic diagrams isn't just beneficial for engineers, but can also be helpful for anyone who is attempting to understand complex electrical systems or wiring. Due to the symbols and lines used in schematics, it is much easier to visualize how the device or circuit works than if the same connections were written out in code.

Schematic diagrams are incredibly useful tools for electrical engineers, technicians, and laymen alike. They provide a simple way to quickly visualise the components of a system and their connections - helping to develop, construct, test, and troubleshoot devices, circuits, and systems more efficiently.
