Practice of Electric Circuits Using Demonstration of Phasor Locus Calculated by Computer

This paper describes practice of electric circuits using demonstration of phasor locus calculated by computer. Textbooks that authors has written have been used for an education of electric circuits at National Institute of Technology, Toyota college. It was carried out that a questionnaire survey whether demonstration of phasor locus calculated by computer was needed for students. The questionnaire survey was also performed whether phasor locus calculated by computer was worth to be seen in class. It is considered that demonstration of phasor locus calculated by computer is useful to be higher degree of satisfaction of students who are learning electric circuits and is not concerned with score of test in electric circuits.
