| What is the node method? |
* Answer
| 1. Method A certain node in the optional circuit is a reference node, and the voltage between other nodes and this reference node is called “node voltage”.The node method uses the node voltage as an independent variable to write the KCL current equation to each independent node column, and obtains (n-1) independent current equations with (n-1) variables to solve the amount to be determined in the circuit.The mutual conductance is always negative; the above equations are solved together and solved.
6. Explain that when there is a pure voltage source branch, the current of the voltage source can be set as a variable, and the corresponding equation is added.When there is a controlled source, the controlled source can be processed as an independent source, after which the control amount of the controlled source is represented by the node voltage and then moved. |
