Validation of Symbolic Expressions in Circuit Analysis E-Learning

Symbolic circuit analysis is a cornerstone of electrical engineering education. Solving a suitable set of selected problems is essential to developing professional skills in the field. A new method is presented for automatic validation of circuit equations representing a student´s intermediate steps in the solving process. Providing this immediate feedback may strongly enhance the training effects. The new method was embedded in a Web-based e-learning system and has proved to be useful in circuit analysis training, both at an introductory level and for more advanced problems in analog electronics.
