An asymmetrical attenuator in Pi formation with resistor values 20, 12 and 8 Ω left to right. Injecting 6 amperes into port 1 of this network produces 24 volts at port 2. The previous attenuator showing port 1 current splitting to 3 A in each branch. Injecting 6 amperes into port 2 produces 24 volts at port 1.
In 1992, a closely related reciprocity theorem was articulated independently by Y.A. Feld [12] and C.T. Tai, [13] and is known as Feld-Tai reciprocity or the Feld-Tai lemma. It relates two time-harmonic localized current sources and the resulting magnetic fields :
Schelkunoff equivalence principle, introduced by Sergei Alexander Schelkunoff, [6] [7] [8] substitutes the closed surface with a perfectly conducting material body. In the case of a perfect electrical conductor, the electric currents that are impressed on the surface won't radiate due to Lorentz reciprocity. Thus, the original currents can be ...
Stanley's reciprocity theorem for generating functions; Reciprocity (engineering), theorems relating signals and the resulting responses including Reciprocity (electrical networks), a theorem relating voltages and currents in a network; Reciprocity (electromagnetism), theorems relating sources and the resulting fields in classical electromagnetism
Reciprocity in linear systems is the principle that a response Rab, measured at a location (and direction if applicable) a, when the system has an excitation signal applied at a location (and direction if applicable) b, is exactly equal to Rba which is the response at location b, when that same excitation is applied at a. This applies for all ...
These coming reciprocal tariff plans will now take center stage after Trump on Monday evening formalized 25% duties on steel and aluminum which are set to kick in on March 12.

Figure 1: Example two-port network with symbol definitions. Notice the port condition is satisfied: the same current flows into each port as leaves that port.. In electronics, a two-port network (a kind of four-terminal network or quadripole) is an electrical network (i.e. a circuit) or device with two pairs of terminals to connect to external circuits.
