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

- 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.

- 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.
