In Circuit Applet, you have two modes: Design mode and Run mode. You can change mode by clicking at "Design" and "Run" buttons at the bottom of the Applet.

Design Mode:

• You can add, move, and remove components from circuit.
• You can add components by clicking at desired components in the toolbar. It takes a little time to load components.
• You can move components by drag and drop.
• You can remove components by pressing "del" key or by clicking the "Clear" button.

Run Mode:

• You can view the properties (voltage, resistance, and current) of components by moving the mouse cursor over them.
• You can change properties (voltage, resistance, etc) of components by clicking at it.

Caution:

You can not connect two or more wires "directly".

If you do, an error message "[name] is not connected properly" appears when you try to run the circuit.
