Reactance (psychology)         
UNPLEASANT MOTIVATIONAL AROUSAL TO OFFERS, PERSONS, RULES, OR REGULATIONS THAT THREATEN OR ELIMINATE SPECIFIC BEHAVIORAL FREEDOMS
Psychological reactance; Reactance theory
Reactance is an unpleasant motivational reaction to offers, persons, rules, or regulations that threaten or eliminate specific behavioral freedoms. Reactance occurs when an individual feels that an agent is attempting to limit one's choice of response and/or range of alternatives.

In logic, mathematics and computer science, especially metalogic and computability theory, an effective methodHunter, Geoffrey, Metalogic: An Introduction to the Metatheory of Standard First-Order Logic, University of California Press, 1971 or effective procedure is a procedure for solving a problem by any intuitively 'effective' means from a specific class. An effective method is sometimes also called a mechanical method or procedure.
Reactance         
WIKIMEDIA DISAMBIGUATION PAGE
Reactance (disambiguation)
·add. ·noun The influence of a coil of wire upon an alternating current passing through it, tending to choke or diminish the current, or the similar influence of a condenser; inductive resistance. Reactance is measured in ohms. The reactance of a circuit is equal to the component of the impressed electro-motive force at right angles to the current divided by the current, that is, the component of the impedance due to the self-inductance or capacity of the circuit.

PRECISELY DEFINED INTEREST RATE
Effective annual rate; Annual equivalent rate; Effective annual interest rate; Annual Equivalent Rate; Effective interest yield; Effective interest
The effective interest rate (EIR), effective annual interest rate, annual equivalent rate (AER) or simply effective rate is the percentage of interest on a loan or financial product if compound interest accumulates over a year during which no payments are made. It is the compound interest payable annually in arrears, based on the nominal interest rate.

MODELING OF COMPOSITE MATERIALS BY APPROPRIATELY AVERAGING THEIR CONSTITUENT PROPERTIES
Maxwell-garnett; Effective Medium Approximations; Effective medium approximation; Effective medium model; Effective medium; Effective medium theory; Effective permittivity and permeability; Maxwell Garnett approximation; Maxwell Garnett formula
In materials science, effective medium approximations (EMA) or effective medium theory (EMT) pertain to analytical or theoretical modeling that describes the macroscopic properties of composite materials. EMAs or EMTs are developed from averaging the multiple values of the constituents that directly make up the composite material.
Effective action         
QUANTUM CORRECTED VERSION OF THE CLASSICAL ACTION
One particle irreducible correlation function; Quantum effective action; One particle irreducible; 1PI
In quantum field theory, the quantum effective action is a modified expression for the classical action taking into account quantum corrections while ensuring that the principle of least action applies, meaning that extremizing the effective action yields the equations of motion for the vacuum expectation values of the quantum fields. The effective action also acts as a generating functional for one-particle irreducible correlation functions.
Foster's reactance theorem         
  • '''Foster's first form of canonical driving point impedance realisation.''' If the polynomial function has a pole at ''ω''=0 one of the ''LC'' sections will reduce to a single capacitor.  If the polynomial function has a pole at ''ω''=∞ one of the ''LC'' sections will reduce to a single inductor.  If both poles are present then two sections reduce to a series ''LC'' circuit.
  • '''Foster's second form of canonical driving point impedance realisation.''' If the polynomial function has a zero at ''ω''=0 one of the ''LC'' sections will reduce to a single inductor.  If the polynomial function has a zero at ''ω''=∞ one of the ''LC'' sections will reduce to a single capacitor.  If both zeroes are present then two sections reduce to a parallel ''LC'' circuit.

ELECTRICAL NETWORK THEOREM
Fosters reactance theorem; Foster Reactance Theorem; Foster reactance theorem; Foster's network; Foster network
Foster's reactance theorem is an important theorem in the fields of electrical network analysis and synthesis. The theorem states that the reactance of a passive, lossless two-terminal (one-port) network always strictly monotonically increases with frequency.

Electrical reactance

In electrical circuits, reactance is the opposition presented to alternating current by inductance and,or capacitance. Greater reactance gives smaller current for the same applied voltage. Reactance is similar to resistance in this respect, but does not lead to dissipation of electrical energy as heat; instead, energy is momentarily stored in the reactance, and a quarter-cycle later returned to the circuit.

Reactance is used to compute amplitude and phase changes of sinusoidal alternating current going through a circuit element. Like resistance, reactance is measured in ohms, with positive values indicating inductive reactance and negative indicating capacitive reactance. It is denoted by the symbol X {\displaystyle X} . An ideal resistor has zero reactance, whereas ideal inductors and capacitors have zero resistance. As frequency increases, inductive reactance increases and capacitive reactance decreases.
