节点法

过程

1. Select reference node (ground) from which voltages are measured.
2. Label voltages of remaining nodes with respect to ground. These are the primary unknowns.
3. Write KCL for all but the ground node, substituting device laws and KVL.
4. Solve for node voltages.
5. Back solve for branch voltages and currents (i. E., the secondary unknowns)

节点分析方法对于包含浮动独立电压源的电路并不适用，此时我们可以将其处理为超节点。
