Circuit theory has been come into being better academic system, however, in the existing textbooks, there are still many different viewpoints for some rather basic concepts such as branch, node and positive or negative of capacitive reactance.

电路理论虽已形成比较完善的学科体系，但现有教材中仍有一些较基本的概念，如支路及节点定义、容抗的正负等，存在不同观点。
