Voltage Nodal and Mesh Current Analysis

This circuit demonstrates voltage nodal analysis. This resource is a good way to practice this form of analysis as you adjust the resistor and voltage source values. You can do this as you click on the element you wish to change and click the wrench icon in the bottom left corner. Then in the bottom right corner there will be a wheel where you can adjust the values with the yellow arrow. Each node voltage is tracked with the following color charts. If you wish to see the node voltages, click on an area outside the circuit and click on the yellow triangle with a t in the bottom left corner. Once you do that, you will see the voltage values displayed. Since it is simulated in DC, you will see constant values graphed across time. You can also click on the graph to close it and see the voltages labeled with their values near their respective nodes. You can also look at the current in the circuit. In each unique branch of the circuit, there are ammeters which track its current. If you would like to track the current, click on the ammeter you are interested in then click on the eye icon in the bottom left. It will show the current on the same graph described above. You can also see the current displayed near each resistor in each branch.
