What Is The Inductor Symbol, Inductor Knowledge

November 01 , 2023 0

I.The Concept OF Inductors

An inductor is a passive electrical device (usually a conductive coil) that introduces inductance into a circuit, which is basically a coil with many windings, usually wrapped around a magnetic core made of a magnetic material, such as iron. The simplest form of an inductor is composed of coils.
The inductance measured in Henry is proportional to the number of turns of the wire, the diameter of the wire ring, and the material or core wire with which the wire is wound.

II.Inductor Unit And symbol

The SI unit of inductance is Henry (H), and the inductance symbol is named after the American scientist Joseph Henry :L

III.Characteristics OF Inductors

Inductors derive their properties from magnetism rather than electricity.
When an electric current flows through a coil (or any wire), it creates a magnetic field in the space outside the wire, attracting iron and other magnets
The coil acts just like any natural permanent magnet

IV.Inductor assembly

It is well known that inductors are combined because they act like resistors, with inductors in series. This makes sense physically because two coils in series look like a longer coil connected in parallel reduces inductance because the current is distributed between several coils, so the magnetic field in each coil is weaker

Classification OF Inductors

Inductors are divided into different types according to their core material and mechanical structure, mainly including the following categories:

Hollow inductance
Core inductance
Ferrite core inductor
Iron power inductors
Inductors based on spool
Ring inductor
Multilayer ceramic inductor
Thin film inductor
Variable inductor
Coupling inductance
Molded inductors

How The Inductor Works

If a wire is passed through a magnetic field, a current will be generated in the wire and flow through the relevant circuit. It takes energy to move a wire through a magnetic field, and the mechanical energy is converted into electrical energy. That's how a generator works.
If the current through the coil is stopped, the magnetic field must also disappear, but not immediately. The field represents stored energy, and that energy has to go somewhere. The field shrinks toward the coil, and a field moving through the coil wire has the same effect as moving the wire through the stationary field: an electric current is generated in the coil.
The role of this induced current is to keep the current flowing in the coil, and the induced current will increase or decrease any change in the current through the inductor. Inductor used in dry circuit
To smooth the current and prevent any rapid changes. The current in an inductor is similar to the voltage at both ends of the capacitor dew. Changing the voltage at both ends of the capacitor takes time, and if you test the flower yourself, you should find that a large current will initially flow.

Similarly, it takes time to change the current through an inductor, such as turning on a switch, which generates a large voltage as it tries to force the current to flow. This inductive electroplast can be very large and can damage other circuit elements, so some elements, such as resistors or even capacitors, are usually connected at both ends of the inductor to provide a current path and absorb the induced voltage. Usually, diodes are also used.
In addition, if an electric current flows through a wire in a magnetic field (generated by a permanent magnet or current flowing through a coil), it creates a mechanical force on the wire, which can also play a role.
In a motor, the wires that pass through the magnetic field and bear the force are also in the form of coils that are mechanically connected to the shaft of the motor. This coil looks like an inductor, but it is actually rented like an inductor. If you turn off the current (stop the motor), the coil will still move in the magnetic field, and the motor will look like a generator at this time, which can produce a large voltage. The resulting induced voltage spike can damage components, such as circuits that control the current of a motor.

Functional Use OF Inductors

Currently inductors are used in a variety of applications, the main functions include:

Filters: Inductors are often used with resistors and capacitors to create filters for analog circuits and signal processing
Sensors: Inductors are used to generate magnetic fields from a distance, and inductive sensors are widely used at traffic light intersections.
Transformer: The combination of inductors makes the transformer smaller and lighter.
Motors: Induction motors use magnetic forces to convert electrical energy into mechanical energy, and these motors are very reliable.
Store energy: Like capacitors, inductors can also be used to store energy, but with some limitations.
