Reactance

Reactance \Re*act"ance\ (r[-e]*[a^]k"tans), n. [React + -ance.] (Elec.) 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.

Wikipedia
Reactance (psychology)

Reactance is a motivational reaction to offers, persons, rules, or regulations that threaten or eliminate specific behavioral freedoms. Reactance occurs when a person feels that someone or something is taking away his or her choices or limiting the range of alternatives.

Reactances can occur when someone is heavily pressured to accept a certain view or attitude. 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. People using reverse psychology are playing on at least an informal awareness of reactance, attempting to influence someone to choose the opposite of what they request.

Reactance

Reactance may refer to:

  • Electrical reactance, the opposition to a change in voltage due to capacitance (capacitive reactance) or in current due to inductance (inductive reactance); the imaginary component of AC impedance
  • Magnetic reactance, a similar effect in magnetism
  • Reactance (psychology), an emotional reaction to pressure or persuasion that results in the strengthening or adoption of a contrary belief
