Electric Networks

An electric network is defined¹ as "a combination of any number of electric elements, the impedances of which may be either lumped or distributed or both, which are connected in any manner, conductively, inductively, or capacitively."

Electric networks may be classified¹ as active electric networks (a network containing one or more sources of energy) or as passive electric networks (a network containing no source of energy). It is understood that a network is passive and contains no source of energy within itself unless the contrary is stated.¹ Passive lumped networks only will be considered in this chapter.
