Electrical Schematic Symbols Explained

By | July 10, 2022



If you’re in the engineering field, then you’ve certainly come across electrical schematic symbols – diagrams or pictures that represent electronic components and their interconnections. These symbols are used in circuit diagrams or wiring diagrams to help visualize how a device or system works. While these symbols can be confusing to newcomers, understanding them isn’t as difficult as it may seem. In this article, we’ll be exploring the basics of electrical schematic symbols, so you can become more comfortable with reading circuit diagrams.

First, let’s start by taking a look at the different types of symbols you’ll encounter. There are five basic categories: power sources, resistors, capacitors, coils, and transistors. Each has its own unique symbol, allowing you to quickly identify what type of component is present.

Next, let’s move on to the individual components within each of those categories. Power sources, for example, have two basic symbols: the triangle, which indicates a source of electricity, and the circle, which indicates a ground. Resistors, capacitors, and coils all have a variety of unique symbols, each with their own specific purpose. Finally, transistors have two distinct symbols: one for an NPN transistor (three vertical lines) and one for a PNP transistor (two vertical lines).

Understanding these symbols makes it much easier to read a circuit diagram. By looking at the shape and orientation of each symbol, you can quickly identify the type of component and its purpose within the circuit. Once you’ve identified each component, you can begin building your own circuit diagram.

By understanding electrical schematic symbols, engineers and technicians are able to create complex circuits and systems from even the most basic diagrams. And while it may require some practice, once you get the hang of it, you’ll be reading these diagrams like an expert in no time. If you’re interested in learning more about electrical schematic symbols, there are plenty of online tutorials and resources available.
