1. (Electronics) the opposition to the flow of alternating current by the capacitance or inductance of an electrical circuit; the imaginary part of the impedance Z, Z = R + iX, where R is the resistance, i = √–1, and X is the reactance. It is expressed in ohms. Compare resistance3
2. (General Physics) the opposition to the flow of an acoustic or mechanical vibration, usually due to inertia or stiffness. It is the magnitude of the imaginary part of the acoustic or mechanical impedance

Alternatively, Tatum, Olsen, and Frey (2018) ground an explanation of persistent student personal technology use in psychological reactance theory; a classroom policy that restricts personal technology use denies student autonomy.
These expected relationships between workplace deviance and the organizational structure (e.g., centralization and formalization) are based on reactance theory (Brehm, 1966) and situational strength theory (Mischel, 1977).
The secondary aim was to assess the influence of height, body weight, and atopic features on the values of reactance and resistance.
In the face of these peculiarities of organ donation (messages) and in line with the entertainment education approach (Moyer-Guse, 2008; Singhal, Cody, Rogers, & Sabido, 2004), we suggest that narratives might be an effective means to convey the relevant information countering specific fears and myths, because narratives have not only been shown to positively influence organ donation attitudes and intentions (Morgan, Movius, & Cody, 2009), but are also less likely to cause selective avoidance and evoke reactance (Green, 2006; Moyer-Guse & Nabi, 2010).
Moreover, we can conclude that the damping torque provided by the proposed design depends greatly on the system loading and the line reactance.
where "Vi' is the voltage of bus "i' and "Vj' is the voltage at bus "j' and "X' is the reactance of the line connecting bus "I' and bus "j' "Vimax' and "Vimin' are maximum and minimum voltage limits and "Vinom' is average of "Vimax' and "Vimin' and "Npq' is total number of load buses in the system[10]
Partisan identification: Reactance theory versus reinforcement theory.
[X.sub.L] is the reactance of the inductor and [X.sub.L]([alpha]) is the effective reactance of the inductor at firing angle a and is limited thus:
Two different situations, the load reactance change and the load resistance change, are considered separately.
Choi SH); (ii) a 30% or more increase in the resistance value at 5 Hz; or (iii) an 80% or more increase in the reactance value at 5 Hz.
In addition, no changes were seen in lung function based on impulse oscillometry, a noninvasive method for measuring airway resistance and reactance (Chest.
It has two components--resistance (R) and reactance (Xc).
