Reactance is a motivational state that is aimed at re-establishment of a threatened or eliminated freedom. In short, the level of reactance has a direct relationship with the importance of the eliminated or threatened freedom, and the proportion of free behaviours eliminated or threatened.
The state is very brief, as the current in the damper winding quickly decays allowing the armature flux to enter the rotor poles only. The generator goes into transient state; in the transient state (′) the flux is still out of the field winding of the rotor. The transient state decays to steady-state in few cycles. [6]
Reverse psychology can fall under many different psychological influence techniques. Reverse psychology is sometimes referred to as psychological reactance, the aroused state that occurs when freedom is threatened or eliminated. The higher stake or more freedoms that are threatened, the more arousal that can be expected.
In electrical engineering, impedance is the opposition to alternating current presented by the combined effect of resistance and reactance in a circuit. [1]Quantitatively, the impedance of a two-terminal circuit element is the ratio of the complex representation of the sinusoidal voltage between its terminals, to the complex representation of the current flowing through it.

In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance. [1] Along with resistance, it is one of two elements of impedance; however, while both elements involve transfer of electrical energy, no dissipation of electrical energy as heat occurs in reactance; instead, the reactance stores energy until a quarter-cycle later when the energy ...
Sensenig & Brehm [7] applied Brehm's reactance theory [8] to explain the boomerang effect. They argued that when a person thinks that his freedom to support a position on attitude issue is eliminated, the psychological reactance will be aroused and then he consequently moves his attitudinal position in a way so as to restore the lost freedom.
Higher SCR requires lower reactance that in practice means a larger air gap. [5]Both high and low levels of SCR have their benefits: [6] low SCR: in case of a short circuit, the current is proportional to SCR, therefore generators with low SCR require less protection and thus are cheaper;
The normalised impedance Smith chart is composed of two families of circles: circles of constant normalised resistance and circles of constant normalised reactance. In the complex reflection coefficient plane the Smith chart occupies a circle of unity radius centred at the origin.
