【Abstract】 The idea of dimensional model of the universe is applicable to any system, including physical systems and electric circuit systems. This paper systematically analyzes and summarizes the basic principles of circuit operation, determines 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.更多还原
