Electrical reactance
- 电抗（交流电路中，电容和电感对电流起阻碍作用，称为电抗，用X表示，是复数阻抗的虚数部分，随着频率变化，引起电路电流与电压的相位变化。阻抗是电阻和电抗的总合，一般电路的总电抗等于感抗减容抗）

abstract:
In electrical and electronic systems, reactance is the opposition of a circuit element to a change of electric 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.
