In the electronic circuit, the inductor coil ACTS on the ac finite current, it and the resistor or capacitor can form high pass or low pass filter, phase shift circuit and resonance circuit, etc. Transformers can be used for ac coupling, transformer voltage, transformer and impedance transformation. By inductance XL=2 fL, inductance L is bigger, frequency f is higher, inductance is bigger. The size of the voltage at both ends of the inductor is proportional to the inductance L, and also proportional to the current change speed I/t, this relationship can also be expressed as follows: the inductor coil is also an energy storage element, it is in the form of magnetic energy storage, the stored energy can be expressed as follows: WL=1/2 Li2. Thus, the greater the inductance of the coil and the greater the flow, the more electric energy will be stored.
