Revision of Mathematical Approach to Electrical Circuit Modelling

Discussion of two possible approaches to the same problem: linear electrical circuits modelling, is used to define the mathematical background students need to establish before they start with the circuit analysis. Classical, analytical approach is compared to numerical one, and the better choice is proposed. Consequences to the teaching, for the moment, are unpredictable but intriguing.An RLC circuit is a frequent example in the most of books about electrical engineering theory fundamentals. Although the circuit is as simple as possible, it is of great educational value. Mathematics needed for the circuit analysis is a core of mathematic modelling used in all other linear electrical circuits analysis. The difference is in number of components and equations complexity, but the principles are the same.
