Top 10 Best Circuit Diagram Makers 2021

If you are into the electrical engineering field, you’d know how important circuit diagrams are when it comes to representing an electrical circuit. With the modernization, the best circuit diagram makers further make the process a lot easier for you to get around with.

circuit diagram makers

Circuit diagrams have been in use since decades, mainly to help plan the layout of the electrical circuit or even to ensure better idea of the blueprint of the process. While engineers drew the blueprints and diagrams by hand back in the day, things have changed now.

With the rapid growth of technology and the use of varying tools for visual representation of the ideas, circuit diagram makers have gained a lot of popularity. These are not just useful in helping improve the overall layout of the diagram but also helps get the process done in no time at all and that too with minimal room for error.

What is a circuit diagram?

For those who have no idea, circuit diagrams are the visual representation of an electrical circuit that is made using basic images of the parts used or even the symbols that are used in the industry.

There are two different types of the circuit diagrams available – the pictorial version and the schematic version. The pictorial version makes use of the standard images of the parts used in the circuit while the schematic version uses the industry level symbols.

The pictorial version is mainly drawn up for the people who have a less of a technical audience and just want to get a visual of the things happening. The schematic version, on the other hand, is mainly targeted for an electrician who is going to work on that circuit and develop it in real time. This is why it is more detailed and contains more symbols for better understanding.
