What is a circuit diagram?

A circuit diagram is a visual representation of an electrical circuit. A pictorial circuit diagram uses images of components (such as photos or sketches), while a schematic diagram shows the components and interconnections of the circuit using standardized symbols.

How to create a circuit diagram in Lucidchart

Determine the goal and the audience of your circuit diagram
Consider whether your audience has professional knowledge of circuit structure and decide whether your diagram should be schematic or pictorial.

Select the shape library and drag and drop components
Select the circuit diagram shape library and begin dragging components onto the canvas. You can also import an image of your circuit for reference.

Draw and format connections
Draw lines between your components representing wire connections. Lines that intersect will automatically show as line jumps, but you can adjust this feature in your page settings for lines.

Drop and designate power sources
Drop a power source component into your diagram and designate its label, orientation, and charge with the pop-up menu when you double-click it.

Review and share
Once you’ve added each element, including connections, ensure the circuit you’ve drawn behaves as expected. Share it with others or publish it in a presentation or as an image file.

Frequently asked questions about circuit diagrams

What shapes and symbols should I use in my circuit diagram, and where can I find them in Lucidchart?

We support all industry-standard symbols in the dedicated circuit diagram shape library, which provides symbols for electrical, power sources, transistors, relays, logic, gates, and more.

I don’t see a specific component I need to use in my diagram within the shape library. How can I get it?

If you don’t see the circuit diagram symbols you want in the provided shape library, you can import custom shapes and images.

How do I format my line connections in Lucidchart?

By default, your lines will automatically connect to components and create line jumps when they intersect. You can modify these and other settings using the formatting bar or by navigating to your page settings.

How can I use Lucidchart to work on a circuit diagram I already have in Visio®?

Anyone can import and view Visio® diagrams in Lucidchart. Users with Individual, Team, and Enterprise Lucidchart accounts can also edit their imported diagrams and export them back into Visio®.

Learn more

What other diagramming platforms does the Lucidchart file import feature support?

Lucidchart allows you to import diagrams Microsoft Visio® (VDX, VSDX, and VSD), Gliffy (GXML, GLIFFY), draw.io (XML), and OmniGraffle (GRAFFLE, GRAFFLE.ZIP).

What is the difference between a schematic and pictorial circuit diagram?

A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components of the circuit as simplified standard symbols—both types show the connections between the devices, including power and signal connections.
