Injecting 6 amperes into port 2 produces 24 volts at port 1. The previous attenuator showing port 2 current splitting to 1.2 and 4.8 A the horizontal and vertical branches respectively. Hence, the network is reciprocal. In this example, the port that is not injecting current is left open circuit.
Transresistance (for transfer resistance), also infrequently referred to as mutual resistance, is the dual of transconductance. It refers to the ratio between a change of the voltage at two output points and a related change of current through two input points, and is denotated as r m:
Its reciprocal quantity is electrical conductance, measuring the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with mechanical friction . The SI unit of electrical resistance is the ohm ( Ω ), while electrical conductance is measured in siemens (S) (formerly called the 'mho' and then ...
The siemens (symbol: S) is the unit of electric conductance, electric susceptance, and electric admittance in the International System of Units (SI). Conductance, susceptance, and admittance are the reciprocals of resistance, reactance, and impedance respectively; hence one siemens is equal to the reciprocal of one ohm (Ω −1) and is also referred to as the mho.
Conductivity is the inverse (reciprocal) of resistivity. ... Typically, lightning discharges 30,000 amperes at up to 100 million volts, and emits light, radio waves ...
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 (electromagnetism), theorems relating sources and the resulting fields in classical electromagnetism; Reciprocity (electrical networks), reciprocity theorem as it relates to current and voltage in electrical networks; Reciprocity (network science), measures the tendency of vertex pairs to form mutual connections between each other
Reciprocity is useful in optics, which (apart from quantum effects) can be expressed in terms of classical electromagnetism, but also in terms of radiometry. There is also an analogous theorem in electrostatics, known as Green's reciprocity, relating the interchange of electric potential and electric charge density.
