Icircuit dependent voltage source simulator#

Giving two nodes the same name is equivalent to drawing a wire between two nodes. You can 'connect' two nodes in your circuit by naming them the same thing. A Name Node can be dropped onto a wire or directly onto any circuit element's endpoint. You can do this by using the Name Node circuit element. It is often very useful (and good practice) to name certain nodes in your circuit. It is perfectly valid (and often more compact) to connect two or more endpoints of a circuit elements together without expcitly drawing a wire between them. By definition, the two endpoints of elements that are connected by a wire have the same voltage. A node in CircuitLab is the same thing: a point where two or more elements that are connected by a wire.

However, inside a circuit simulator (or even when solving a circuit on paper!), we have to pick one node to be our reference in order to calculate voltages at other nodes.Ī node in an electrical circuit is a place where two or more circuit elements meet. In real life, ungrounded battery-operated circuits work just fine, because to the circuit, only relative voltages matter. The concept of a ground in a circuit simulator is similar but not identical to the concept of an electrical ground in the physical world. This means that every circuit has to have at least one GND element, or the circuit will not simulate. CircuitLab is not compatible with browser zoom, and currently has no way to detect this condition.)Įvery voltage in CircuitLab is calculated relative to the ground ( GND) node, which is by definition at 0 volts. (Note: please avoid holding Ctrl while actuating the mousewheel, as this generally causes the browser to attempt to zoom on its own. Holding down the Ctrl key while clicking and dragging on the grid will allow you to pan the viewport. You can switch to Simulate Mode by clicking the 'Simulate' button along the bottom toolbar.Ĭlick a component in the Build Box to select it, and then click somewhere on the grid to insert into your circuit.ĭouble-click any component in your circuit to bring up the corresponding parameter editor.
