Definition, Meaning & Synonyms
reactance
noun
/rɪˈaktəns/
Definition
The resistance of a circuit to the flow of alternating current, which arises from the capacitive or inductive properties of components in the circuit.
Examples
- The reactance of the circuit increased at higher frequencies.
- Inductors have a positive reactance, while capacitors have a negative reactance.
- Understanding reactance is crucial for analyzing AC circuits.
Meaning
Reactance is a measure of how much a circuit resists the flow of electric current when the current is alternating, due to the capacitive or inductive elements present.
Synonyms
- Impedance
- Resistance (in the context of AC)
- Capacitance (when referring to capacitive reactance)
