What is the color ring inductance
Color ring inductance, also known as color code inductance, color ring inductance, is a kind of element using self-inductance.In the circuit, the inductance coil (color ring inductance) is usually composed of resonance circuit and filter circuit together with capacitor.
The basic principle of color ring inductance is charge and discharge, of course, there are rectification, oscillation and other functions.
Color ring inductance is generally used for circuit matching and signal quality control, general connection and power supply connection, is also a kind of energy storage element.
The change of inductance of color ring comes from the change of external alternating power supply.
In a word, when the color ring inductor is connected to the ac power supply, the magnetic field line inside the color ring inductor will be constantly changing with the alternating current, causing the color ring inductor to generate electromagnetic induction.The electromotive force generated by the change of the current of the inductance itself is called the color ring inductance.
The role of color ring inductance in a circuit
The color ring inductor has the function of tuning and frequency selection.
In resonance, the inductive reactance and capacitive reactance of the circuit are equivalent and reverse, that is, the natural oscillation frequency f0 of the circuit and the frequency f of non-ac signal are equal, the inductive reactance and capacitive reactance of the circuit are also equal, the use of the general is not very high, in general, the use of color ring ring in the circuit is relatively stable.
The copper core in the coil always resists the change in current in the coil.Resistance to the ac current used in the circuit, the size of the resistance is called inductive resistance XL, in ohms.
The relation between it and inductance L and ac frequency f is XL=2 PI fL, which can be divided into high-frequency choke coil and low-frequency choke coil.It is mainly used to screen signal, filter noise, stabilize current and restrain electromagnetic wave interference.
The basic function of inductors is to charge and discharge, but many circuit phenomena extended by this basic charge and discharge function make the inductors of color ring have various USES.
The inductance represents the intrinsic characteristics of the coil, independent of the current.Except for special coils, the sensor is usually not specially labeled on the coil, but labeled with a specific name.
Color ring coil is a high-frequency coil, which is wrapped with some enameled wires on the magnetic core and then sealed with epoxy resin or plastic.
Its operating frequency ranges from 10khz to 200mhz, and its inductance generally ranges from 0.1uh to 3300uh.
Color code inductors are sensors with fixed inductance, which are marked by color rings as well as resistors.The units are uh.
The principle of color ring inductance
The basic principle of the color ring inductor is charge and discharge, of course, there are rectification, oscillation and other functions.Not only do power supply connections signal quality control and matching circuits, and common connections, color ring inductors are commonly used in storage components.A spark occurs, which is caused by the high inductive potential of the ring inductance.
"Inductor" turning moment or broach switch knife switch, higher inductance potential caused by self-induction.From an objective point of view, the color ring inductance change is from the external ac power supply, prevent the current change characteristic color ring inductance ac circuit.
In short, if the color ring inductance is connected to the ac power supply, the moment when the color ring inductance changes with the magnetic field line inside the ac current is the result of electromagnetic induction.
