Circuit Design - Simulation

DC/AC Virtual Lab

If you are a student or hobbyist and interested in experimenting with electric circuits or an instructor who is willing to test electric circuits to teach in class room, DC/AC Virtual Lab is an online simulator who is capable of building DC/AC circuits, you can build circuits with batteries, resistors, wires and other components, then compute Volt, Ampere, Ohm between at any component or connections nodes at board.

Java Circuit Simulator

This is an electronic circuit simulator. When the applet starts up you will see an animated schematic of a simple LRC circuit. The green color indicates positive voltage. The gray color indicates ground. A red color indicates negative voltage. The moving yellow dots indicate current.

EveryCircuit

EveryCircuit is an easy to use, highly interactive circuit simulator and schematic capture tool. Real-time circuit simulation, interactivity, and dynamic visualization make it a must have application for professionals and academia. EveryCircuit user community has collaboratively created the largest searchable library of circuit designs. EveryCircuit app runs online in Chrome browser and on mobile phones and tablets, enabling you to capture design ideas and learn electronics on the go.
