Circuit Simulator


The JAVA Applet Analog Circuit Simulator applet was written by Paul Falstad.

I leverage Paul's JAVA Applet to create circuits encountered while I watch videos, interprete wiring diagrams, and read text books.

Please visit Paul's web site to learn more about it. Visit Paul's Web Site
In addition, you can find other useful JAVA Applets on his web site.

This java applet 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. To turn a switch on or off, just click on it. If you move the mouse over any component of the circuit, you will see a short description of that component and its current state in the lower right corner of the window. To modify a component, move the mouse over it, click the right mouse button (or control-click if you have a Mac) and select “Edit”.
