The study of circuits is the foundation on which most other courses in the electrical engineering curriculum are based. For this reason the first course in circuit analysis must be appropriate to the succeeding specializations, which may be classified into two groups. One is a specialization in electro nics, microelectronics, communications, computers etc., or so-called low current, low-voltage engineering. The other is in power electronics, power systems, energy conversion devices etc., or so-called high-current, high voltage engineering. It is evident that although there are many common...
