Dimensional Models of Electric Circuits and Principles of Similarity and Duality
The idea of dimensional model of the universe is applicable to any system,including physical systems and elec-tric circuit systems.This paper systematically analyzes and summarizes the basic principles of circuit operation,deter-mines the dimensions of circuit system,proposes concepts such as the dimensional model,similarity principle,duality principle,and law extensibility principle of circuits,and provides some practical cases manifesting similarity principle and duality principle.
