Online Electronic Circuit Simulator

Build and test electronic circuits right in your browser - no software installation required
Yes. You can save your circuit in several ways. You can save it as a file, export it as a link, or export the circuit data as text and import it later.
On a computer, move the mouse cursor over the desired point or wire in the circuit. On a mobile device, tap the desired point or wire. The voltage at that point will be displayed.
Yes. You can export the circuit as a PNG image using the "Export as Image" option in the File menu.
On a computer, right-click on the circuit to open the component menu and select the desired component. On a mobile device, open the "Draw" menu and select the component you want to add.
Yes. The simulator includes a collection of ready-made circuits for learning and practice. Open the "Circuits" tab, where the circuits are organized into several sub-tabs for easy browsing. Select a circuit to load it into the simulator and explore how it works.

Electronic Circuit Simulator is an interactive online tool for real-time electrical circuit modeling. With this service, you can build a circuit from basic components: resistors, capacitors, transistors, inductors, diodes, logic gates, and power sources. You will immediately see how currents and voltages distribute across it.

The tool visualizes circuit behavior with animation: charge movement is shown as moving dots along the conductors, and a built-in virtual oscilloscope lets you observe the waveform at any point in the circuit. This makes the simulator equally handy for educational purposes, such as learning the fundamentals of electrical engineering and electronics. It is also useful for quickly testing ideas before assembling a physical device.

This circuit simulator will be useful for engineering students, hobbyists, physics and electronics teachers, and engineers who need a fast sanity check on a simple circuit without firing up a full-fledged CAD package. All computations run right in your browser. No sign-up or extra software installation is required.
