课程名称：电感特性 课程概述： 本课程将详细讲解电感原理和感抗。通过电路示例，我们将展示纯电感电路中电流和电压的变化规律，以及当电路中串联电阻时，这些特性如何随之改变。此外，课程还将探讨交流电源电压的频率对电压与电流相位角的影响。 **什么是电感？** 电感是指导电体因电流流动而产生磁场，并试图阻止流经自身电流的改变的特性。导体周围的磁场强度取决于电流的大小，并随电流变化而改变。 **什么是感抗（XL）？** 感抗（或称电抗）是电感电路对电流的阻碍作用。电感器的线圈对电流的改变会形成一种与之对抗的力量，这种对抗作用类似于电阻，但它总是伴随着电压与电流之间的相位差，并且不消耗能量。感抗的缩写为XL，信号的频率会影响XL的值。 **简单来说，感抗就是电感电路的电阻！** 教学大纲：无
This Course Explains the principle of Inductance and Inductive Reactance. The Circuit Examples will show how Current and Voltage are affected in a Pure Inductive Circuit and How these properties change as Resistance is added to the the mix,in addition to this frequency of the Ac source voltage will be discussed and will show how the phase angle between the Voltage and current will be affected.What is Inductance ? Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the magnitude of the current, and follows any changes in current.What is Inductive Reactance (XL) ? Inductive reactance or simply reactance is not anything but the resistance of an inductive circuit. An inductor competes against the current in a coil which alters the direction and instantaneous magnitude. This opposition is comparable to resistance but always possesses a phase shift between voltage and current and dissipate zero. The abbreviation of Inductive reactance is XL, frequency of the signal will effect the value of XL.Simply Put Inductive Reactance is Simply the Resistance of an Inductive circuit!
