The purpose of this paper is to develop the concept of modes in linear circuits. It is well known that the chapter on modes in lossless circuits or in conservative mechanical systems belongs naturally to any good text on the subject. The contribution of this paper is to show that provided a suitable point of view is taken, the concept of modes does apply indeed to any linear circuit:more precisely, it will be shown that it applies to any lossy or lossless, active or passive., reciprocal or nonreciprocal circuit. The inportance of the mode concept lies in the fact that it allows one to consider a linear circuit as a whole, to break up its behavior as a sum of very simple patterns, and to visualize easily the effect of ex¬ternally applied forces. Futhermore it provides a very informative des¬cription of the resonance phenomenon.
