Definitions

from The American Heritage® Dictionary of the English Language, 4th Edition

  • n. Electricity Opposition to the flow of alternating current caused by the inductance and capacitance in a circuit rather than by resistance.

from Wiktionary, Creative Commons Attribution/Share-Alike License

  • n. The opposition to the change in flow of current in an alternating current circuit, due to inductance and capacitance; the imaginary part of the impedance.
  • n. An emotional reaction in direct contradiction to rules or regulations that threaten or eliminate specific behavioral freedoms.

from the GNU version of the Collaborative International Dictionary of English

  • n. 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.

from The Century Dictionary and Cyclopedia

  • n. In electricity, the apparent resistance of an alternating-current circuit due to self-induction, which consumes no power; the ratio of the wattless component of the alternating electromotive force divided by the current. See impedance.

  • (Psychology) "Reactance is an emotional reaction in direct contradiction to rules or regulations that threaten or eliminate specific behavioral freedoms. It 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." wikipedia
