Reactance may refer to: *

Electrical reactance In electrical circuits, reactance is the opposition presented to alternating current by inductance or capacitance. Greater reactance gives smaller current for the same applied voltage. Reactance is similar to resistance in this respect, but does ...

, 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
