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

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
