Abstract:
Numerical Time Domain electrical circuit simulators are the de facto standard in industry and education. Nevertheless circuits simulators based on symbolic or qualitative techniques have been equally studied. These latter techniques aim at simulating the mental models that an experienced engineer taps when manually designing and analysing a circuit. This paper describes the development of two software tools based on symbolic and qualitative analysis and their use as an electrical circuits eTutor is studied and discussed. As a comparison the paper also investigates the limitations and drawbacks of time domain electrical circuit simulators when used as a pedagogical tool. The field tests are carried out with the engagement of polytechnic teachers and students at the higher national diploma level.
