电抗 Electrical reactance

(重定向自Capacitive reactance)

类似于直流电路中电阻对电流的阻碍作用,在交流电路(如串联RLC电路)中,电容及电感也会对电流起阻碍作用,称作电抗(Reactance),其计量单位也叫做欧姆。在交流电路分析中,电抗X 表示,是复数阻抗的虚数部分,用于表示电感及电容对电流的阻碍作用。电抗随着交流电路频率而变化,并引起电路电流与电压的相位变化。

Electrical reactance 电抗

(重定向自Capacitive reactance)

In a electrical and electronic systems, reactance is the opposition of a circuit element to a change in current or voltage, due to that element's inductance or capacitance. A built-up electric field resists the change of voltage on the element, while a magnetic field resists the change of current. The notion of reactance is similar to electrical resistance, but it differs in several respects.
