Also known as reactance

由于元件的电感或电容,电路元件与电流或电压的变化相反

AI overview

Electric reactance is the resistance that inductors and capacitors provide to changes in electric current flowing through a circuit. It matters because it affects how circuits respond to alternating current, determining how much the current and voltage get out of sync with each other.

在交流电路(如串联RLC电路)中,电抗(英語:Reactance)是类似于直流电路中电阻对电流的阻碍作用,用於描述电容及电感对电流的阻碍作用,其计量单位也是欧姆。在交流电路分析中,电抗用 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。
