Equivalent Pi-typed circuit simulation to reciprocal two-ports

By means of simulation tools, this paper introduces a new viewpoint to understand the re- ciprocal theorem on two ports of resistors. Then discussing a simplification idea from a unclear two ports network to a clear Pi-typed resistor circuit, the author represents both simplification steps and a decision standard about it. The exercise result shows, with the content getting easier and its perceptual grade rising, the means can make two ports theorem easily understood and efficiently applied by learn- er.
