Electrical Components Symbols And Functions

By | December 23, 2021



Understanding the various electrical components symbols and functions is important for anyone working in the electrical engineering and construction industry. The symbols are used to denote the type of component and its function within a circuit; they help to make diagrams easier to interpret, helping those in the industry to quickly identify the components needed for a particular project. This article will discuss the most common electrical components symbols and their associated functions, providing an understanding of what each symbol means and how it is used.

Modern electrical engineering and construction requires a detailed knowledge of how components fit together and interact in order to create efficient systems. Symbols provide an efficient way to represent the various components and their connections. A basic understanding of the symbols used is essential for anyone working in the field, as being able to accurately interpret diagrams is key for any project.

The use of electrical components symbols dates back to the 18th century when engineers would sketch out their designs on paper. As the complexity of electrical systems increased, the need for a standardised system of symbols became apparent, leading to the development of the American Standard Code for Information Interchange (ASCII) in 1968. Over the years, various other symbols have been created but the ASCII symbols remain the most commonly used in the industry. Let’s take a look at some of the most common electrical components symbols and their functions.
