Definitions for "Reactance"
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.
Brehm summarised his Theory of Psychological Reactance by saying "In general, the theory holds that a threat to or loss of a freedom motivates the individual to restore that freedom. ... The theory stipulates what constitutes a freedom, how freedoms can be threatened or eliminated, and how the ensuing motivational state (psychological reactance) will manifest itself." The theory also associates the state of reactance with emotional stress, anxiety, resistance and struggle for the individual, and is a powerful model for understanding the behaviour of slaves as their freedoms are progressively removed.

That part of the impedance of an alternating current circuit which is due to capacitance or inductance.
