Circuit Builder
(beta)

Notes:
Drag the circuit elements into the schematic.
Right click on the components after you place them in the circuit.

Circuit Builder simulates AC and DC circuits.  It was written by by Toon Van Hoecke at the Universiteit Gent.  Circuit Builder can be used in interactive mode (see above) or it can be scripted using JavaScript (see the demo pages). In order for scripting to work, Circuit Builder requires a Java 1.1 capable browser with JavaScript to Java scripting capability.

Circuit Builder is free for non-commercial educational use as outlined in the conditions of use.
