What is Coil ？
何谓线圈
Resistor
（レジスタレジスタ））
电阻Capacitor (キャパシタキャパシタ))
电容
Coil (Inductor)
线圈ＬＲ
Ｃ
Coil (Inductor) is one of passive component,
which is the same as Resistor and Capacitor.
线圈线圈（（电感电感））和电阻和电阻、、电容一样是别动器件之一

Conductor
For DC and AC, the value of resistance is greatly different according to the formula below.线圈的阻抗对于直流和交流有很大的不同
The DC current can pass through completely （if f ＝0 ,then Z L =0）
Whether the AC current can pass through is determined by its frequency.
直流的电流完全能通过直流的电流完全能通过（（由于f=0 Z L =0）
交流电则要根据频率来决定是否通过Z L ＝２πf L
Therefore ,
it is ud to parate DC from AC.
根据这个原理根据这个原理，，线圈用于交直流的区分
