| 单词 | reactance |
| 释义 | reactance Symbol X. A property of a circuit containing inductance or capacitance that together with any resistance makes up its impedance. The impedance Z is given by Z2 = R2 + X2 , where R is the resistance. For a pure capacitance C, the reactance is given by XC = 1/2πfC , where f is the frequency of the alternating current; for a pure inductance L, XL = 2πfL . If the resistance, inductance, and capacitance are in series the impedance Z = v[R2 + (XL - XC)2 ]. Reactance is measured in ohms |
