Definitions of reactance word

  • noun reactance Electricity. the opposition of inductance and capacitance to alternating current, expressed in ohms: equal to the product of the sine of the angular phase difference between current and voltage and the ratio of the effective voltage to the effective current. Symbol: X. Compare capacitive reactance, inductive reactance. 1
  • noun reactance Acoustics. acoustic reactance. 1
  • noun reactance the opposition to the flow of alternating current by the capacitance or inductance of an electrical circuit; the imaginary part of the impedance Z, Z = R + iX, where R is the resistance, i = √–1, and X is the reactance. It is expressed in ohms 0
  • noun reactance the opposition to the flow of an acoustic or mechanical vibration, usually due to inertia or stiffness. It is the magnitude of the imaginary part of the acoustic or mechanical impedance 0
  • noun reactance opposition to the flow of alternating current in a circuit or circuit element, caused by inductance or capacitance and measured in ohms: symbol, X 0
  • noun reactance Reactance is a form of opposition that electronic components exhibit to the passage of alternating current because of capacitance or inductance. 0
