Yes. The free plan includes 5 circuits with up to 20 components each, which is enough for most coursework and learning. Pro and Teacher plans offer unlimited circuits, recordings, classroom tools, and more storage.
Yes. Open Circuits runs entirely in the browser and is optimized for Chromebooks, iPads, and other devices commonly used in schools. No software installation is required.
Absolutely. Many university instructors use Open Circuits for digital electronics, circuit analysis, and electrical engineering courses. The Teacher plan includes classroom management, assignments, and interactive recordings.
Open Circuits supports both digital logic (AND, OR, NOT, flip-flops, multiplexers, etc.) and analog circuits (resistors, capacitors, diodes, transistors, op-amps). The digital engine evaluates logic propagation in real time, while the analog engine uses Modified Nodal Analysis for accurate voltage and current calculation.
No. Student circuits are private by default. Only teachers can view student submissions within assigned work. The public circuit library is curated by admins and contains only reference designs, not student work.
All circuit data is stored securely in the cloud. You can access your circuits from any device by logging in. Circuit files are small (a few KB each) and your data is never shared with third parties.
Circuits are saved in Open Circuits' native format in the cloud. Export to image (PNG) is available from the editor toolbar for including circuit diagrams in reports and presentations.
