Two-Terminal Network

an electrical circuit with two terminals. Two-terminal networks are divided into active networks, which contain a source of electromotive force (emf), and passive networks, which have no source of emf. An active two-terminal network is equivalent to a generator with an emf equal to the open-circuit voltage U_oc and a differential resistance Z = U_oc/I_sc(I_sc is the short-circuit current). A passive two-terminal network, which is only a load element, is characterized by the following external resistance: for alternating current, Zω = Uω/Iω, where ω = 2πf (f is the frequency of the alternating current in hertz); for direct current, r =U/I . A two-terminal network is a special case of a network.
