The role of color code inductance in the circuit
1. There is a layer of insulating material between the two conductors of the color code inductor. Electric charges cannot pass through. Under the action of an electric field, the conductors on both sides accumulate charges of the opposite sex. If it is a direct current, there will be no more current after charging. This is even a direct current blocking effect. If AC is applied, due to the charging and discharging effect of the capacitor, the charging charge will change from time to time with the voltage direction, and the current will change accordingly. Once it is charged and discharged, it is as if the current flows through the capacitor. This is coupling.
2. The tuning loop is a parallel loop of the color code inductor. The current of the color code inductor cannot jump. It forms when there is no voltage outside the loop and current flows to the capacitor to charge. When the potential energy of the color code inductor is released, the capacitor has been charged. , It discharges to the inductor, and the inductor charges the capacitor in reverse. In this way, oscillation is formed. If the frequency of the external signal is equal to the oscillation frequency of this loop, resonance will be caused. Electricity is also called resonance.
3. It can be used for frequency selection, tuning and filtering. What happens in this loop is the potential energy (in the inductor) and the variable electric field energy (in the capacitor). Electric field energy (in capacitance) changes potential energy (in inductance). The time delay is achieved by connecting a resistor in the capacitor charging circuit to limit the charging current to reach the necessary time for the capacitor to be fully charged.
4. Color code inductance (or inductance) is a physical quantity that characterizes the ability of an inductor to hold charge. The amount of electricity we need to increase the potential difference between the two plates of the inductor by 1 volt is called the capacitance of the capacitor. In terms of physics, the color code inductor is a static charge storage medium (just like a bucket, you can charge and enter the charge, in the case of no discharge circuit [1], eliminate the dielectric leakage and self-discharge The effect/color code inductance is significant, and the charge may exist permanently. This is its characteristic), it has a wide range of uses, and it is an indispensable electronic component in the electronics and power fields. Mainly used in power supply filtering, signal filtering, signal coupling, resonance, DC blocking and other circuits.
