1. The color code inductor has the functions of boost and energy storage.
2. There is an insulating film between the two conductors of the color ring inductor, and the charge can not pass through. Under the action of electric field, the conductors on both sides accumulate anisotropic charges, which are direct current. When charged, there will be no current any more. This is the effect of DC isolation. If AC is added, the capacitor will charge and discharge. With the different direction of the voltage, the charge will change from time to time, and the current will change. Once charged and discharged, it is similar to the current passing through the capacitor. That is coupling.
3. The inductance of color-coded inductor has different impedance for different frequency current. Even if the signal of different frequency is selected, it will result in filtering and bypass.
4. Tuning circuit is a parallel circuit of color-coded inductance. The current of color-coded inductance can't jump. When there is no voltage outside, the circuit still has current flowing to capacitor charging. The potential energy of the isochromatic inductance is released. The capacitor once charged and discharged to the inductance, and the inductance charges the capacitor in reverse direction, which forms an oscillation. If the frequency of the signal is equal to the oscillation frequency of this circuit, it will cause resonance, which is also called resonance in electricity.
5. It can be used for frequency selection, tuning and filtering. What happens in this circuit is that potential energy transforms electric field energy. Electric field energy changes electric potential energy. Delay is achieved by using series resistance in the capacitor charging circuit to limit the charging current and achieve the necessary time for capacitor to be full of electricity.
6. The color ring inductance is a physical quantity that characterizes the ability of inductors to hold charges. We call the capacitance of a capacitor the amount of electricity required to increase the potential difference between the two plates of an inductor by one volt. From the physical point of view, color code inductor is a kind of static charge storage medium. The color code inductor which eliminates the leakage and self-discharge effect of dielectrics can be measured remarkably, and the charge may exist permanently. This is its characteristic. It has a wide range of uses and is an indispensable electronic component in the field of electronics and electric power. It is mainly used in power filter, signal filter, signal coupling, resonance, DC isolation and other circuits.
