It can occur when someone is heavily pressured to accept a certain view or attitude. Reactance - What does reactance stand for? The only extra thing to remember when etc. We would like to show you a description here but the site won’t allow us.
The many ways people affect one another, including changes in attitudes, beliefs, feelings, and behavior resulting from the comments, actions, or even the mere presence of others. The Relevance of Reactance Theory This paper suggests how a theory, psychological reactance, developed and tested within experimental social psychology, may be employed to provide a new perspective from which to understand political behavior. Suggest new definition.
L = 1/ω 2 C as L is variable here.
( rɪˈæktəns) n. 1. The reactance to the circuit is the opposition in the flow of varying current. Haidt, J. Thus for the above value of transformer inductance L, resonance will take place.
Greater reactance leads to smaller currents for the same applied voltage. boomerang effect. Reactance can cause the person to adopt or strengthen a view or attitude that is contrary to what was intended and also increases resistance to persuasion. See other definitions of X.
This book discusses a number of special topic areas to which the reactance theory seems especially relevant. In a purely resistive circuit Ohms law applies and V= IR.
Inductive reactance can be defined as the opposition cause by an inductor to the flow of current from an alternating waveform. Using Brehm’s description of reactance, it is “a motivational state and as such is assumed to have energizing and behavior-directing properties” ( Brehm & Brehm, 1981, p. 98 ). Using impedance triangle we can find the resistance if the impedance and reactance is known. : the part of the impedance of an alternating-current circuit that is due to capacitance or inductance or both and that is expressed in ohms.
Reactance varies with the frequency of the electrical signal. As the frequency approaches infinity the inductors reactance would also increase to infinity acting like an open circuit. Voltage drops in the windings occur due to impedance of transformer.Impedance is combination of resistance and leakage reactance of transformer. Looking for online definition of reactance or what reactance stands for?
This 4-hour course provides a basic overview of reactance theory, with emphasis placed on calculating inductive and capacitive reactance and impedance in AC circuits, as well as reactive and true power. Reactance can cause the person to … From the above equation for inductive reactance, it can be seen that if either of the Frequency or Inductance was increased the overall inductive reactance value would also increase. Definition: The instrument which measures the storage factor or quality factor of the electrical circuit at radio frequencies, such type of device is known as the Q-meter.The quality factor is one of the parameters of the oscillatory system, which shows the relation … Reactance is a psychological defence mechanism that we utilise more or less subconsciously in order to try and get … Reactance is an unpleasant motivational arousal to offers, persons, rules, or regulations that threaten or eliminate specific behavioral freedoms. Impedance Triangle is a right angle triangle whose sides represent the impedance. Susceptance is the reciprocal of reactance (good for pure inductors and capacitors) and admittance is the reciprocal of impedance (totally general), and that's as close as you'll get. The unit Ohm for resistance is independent of frequency; it is just the ratio of voltage to current. • … It comprises concepts and their definitions, as well as, a reference to existing theory and scholarly literature that will be used in a particular study. We install a current limiting reactor in feeders and ties, in generator leads, and between the bus sections to reduce the magnitude of short-circuit currents and also to reduce … Mathematically, ωL = 1/ωC. An example of such behavior can be observed when an individual engages in a prohibited activity in order to deliberately taunt the authority who prohibits it, regardless of the utility or disutility that the activity confers. Psychological reactance is a cognitive bias that was initially studied by Brehm in 1966 that describes the extreme reactions human beings experience when we feel as though we are being pushed towards doing something or as though our freedom to make our own choices is being threatened.
Where: ƒ is the Frequency and L is the Inductance of the Coil and 2πƒ = ω. Just like resistance, the unit of reactance is the Ohm. The symbol for reactance is X.
Inductors are typically available in the range from 1 µH (10-6 H) to 20 H. Many inductors have a magnetic core made of ferrite or iron inside the coil, which is used to increase the magnetic field and thus the inductor’s inductance.. According’s to Faraday’s law of electromagnetic induction, when an electric current flowing through an inductor or coil changes, … Reactance is essentially the inertia against the motion of electrons in an electrical circuit i.e.
(page 271) Term. The capacitive reactance depends on the frequency. Psychological reactance. As the frequency approaches infinity the inductors reactance would also increase to infinity acting like an open … Often, armature reactance and self-inductance are combined into the synchronous reactance of the machine: X X X SA V E jX I RI I A S A A Therefore, the phase voltage is The equivalent circuit of a 3-phase synchronous generator is shown. Reactance theory is a standard psychological belief that we see today in countless ways. It is expressed in ohms. Definition of Reactance. Symbol: X … First introduced by Brehm (1968), this theory posits that individuals believe they have certain freedoms and choices and if these are threatened then negative reactions occur. Reactance theory is a concept in social psychology which holds that people will react against attempts to curtail their choices and influence their decisions by finding the object of these restrictions ever more attractive, and by adopting an opposing viewpoint as a way of resisting pressure. The reactance and narcissism components of the theory may seem independent, but there are several overlaps. In the RC Network tutorial we saw that when a DC voltage is applied to a capacitor, the capacitor itself draws a charging current from the supply and charges up to a value equal to the applied voltage. The behavior of the capacitor is different for AC and DC. 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. After high school, he served in the Navy and then attended Harvard College. Psychological reactance occurs in response to threats to perceived behavioral freedoms. the idea that people become upset when their freedom is threatened or eliminated, so much so that they attempt to reassert their lost freedom.
It is basically a geometrical representation of circuit impedance.. Reactance theory assumes there are "free behaviors" individuals perceive and can take part in at any given moment. Definition. Definition and Basic Reactance Concepts According to the theory, if individuals feel that any of their free behaviors, in which they can engage at any moment or Reactance can occur when someone is heavily pressured to accept a certain view or attitude. Haidt, J. 1 A General Reference Work on Telephony, etc. Reactance, X. Reactance (symbol X) is a measure of the opposition of capacitance and inductance to current. Engage in the new restricting attitude or behavior. Specifically, the role of affect was explored within the framework of psychological reactance theory, delineating salience of affect as a driver of the intention to … The theory that explains how the relationship a child has with a caregiver with an early age can impact their behavior in relationships later in life is known as: a. Hyperpersonalization theory b. Relational maintenance theory c. Categorization theory d. Attachment theory e. Development-interactionist theory Psychological Reactance: A Theory of Freedom and Control provides information pertinent to the fundamental aspects of reactance theory. "free behaviors" individuals perceive and can take part in at any given moment. on the theory warrant reconsidering the nature of reactance using contemporary constructs that are amenable to direct measurement. thus does not deal with gene ral moral principles but rathe r. The simplest theoretical framework definition describes it as a collection of theories or interrelated concepts. There are two types of reactance: capacitive reactance (X c) and inductive reactance (X L). Capacitive Reactance is the complex impedance of a capacitor who’s value changes with respect to the applied frequency. Psychological Reactance Theory (Brehm 1966) accounts for how individuals become aversively aroused when perceived freedoms are threatened by overtly persuasive messages.
Thus for the above value of transformer inductance L, resonance will take place. The adjustable resistor R adj controls the field current and, therefore, the rotor magnetic field. Any device in which wire is wound circularly is an inductor. This resonance is called Ferroresonance. social influence. Reactance Theory. Definition and Basic React ance Concepts. Psychology Glossary. It seems like human nature if someone tells us no, that we feel controlled and want to rebel. The righteous mind: Why good people are divided by …
Description. There are two types of reactance: capacitive reactance (Xc) and inductive reactance (X L). Reactance Definition and Meaning: Reactance is a disagreeable emotional and cognitive reaction that results from the restriction of one’s freedom. Academic Press.
http://www.theaudiopedia.com What is REACTANCE?
To specify a specific type of reactance, a subscript is used.
Reactance is operationalized as an amalgam of anger and negative cognitions ( Dillard and Shen, 2005 ), preceded by a freedom threat ( Quick and Stephenson, 2008 ). Resistance is unaffected by the rate of change of voltage or current and remains the same whether DC, or AC of any frequency is applied. Reactance has both magnitude and phase values, and further separates into inductive and capacitive components. Reactance . This resonance is …
