What is inductor and how it works

Very few people know about the inductor, but those who do the work of electronic know it. In today's article, we are going to know what is a inductor and how it works. This is the electronic component that is used very much. By the way, because of this our equipment is able to run continuously and there are many such devices which have been able to be made only with the help of this inductor. With the help of this inductor, DC power supply is continuously in the circuit, so let's know about this with more details.

What is inductor :

The inductor is called a static device that continues to operate without moving and moving. When it is run with electric energy, then it is stored inside it with the help of magnetic field, after which only a small amount of current is present inside it. With the help of this magnetic field, the DC current which grows through the constants further and it also helps in sending the power from one place to another. Inductor is not a big device but a small device that works only on dc current.

What is inductor

What Inductor does :

We will tell you about all the works by inductor which mainly does four tasks and in turn.

Most of its main work is to constrain dc power. Perhaps you do not know that the power we produce from a dc generator does not get dc current constant. Not getting a Constant means that the current comes first, then does not come, then comes and then does not come again. The power generated from the generator keeps on and off several times. So if we run a device by making current from this dc generator directly, then it will turn the device off and on many times because the constant generator is not coming continuously or cannot be found continuously. Due to this, the equipment is unable to run for a long time. To get a current constant, it is applied to the inductor, which sends the current coming from the back and then forward it so that the equipment can run continuously. This is the main job of the inductor.

Apart from this, the second main function of this inductor is to increase the voltage. Some devices are such that the dc current from outside is low but we need more voltage to operate that device. Inductor is also used at that time. So if the equipment is running at a higher voltage then we can also increase the voltage using the inductor at that time.

Now the third feature of this inductor is that it also works well in wireless systems. When the power is to be sent from one circuit to another without any wire, this inductor also comes in handy which easily transfers the power without any wires. This feature is the biggest of this inductor.

The fourth function of this inductor is that it serves to send the signal. If something is to be sent from one circuit to another, then this inductor sends it with the help of tricolor.

Note :

But you must keep in mind that the inductor runs only on the dc current, that is, it cannot work on the ac current.

How Inductor works :

First of all, you should know that the inductor runs only on dc current. So first of all it has to flow dc current in this inductor. According to the diagram, the magnetic field is formed around that inductor as the dc current flows through it. The magnetic field is called the magnetic field itself. Accumulates in the same magnetic field but only in very small amounts.

If you wake the bulb from the same inductor then the bulb will wake only for a short time but not for a long time. In this, you do not think that by making the inductor, you will use it by charging it like a battery, it will not happen because it is stored as long as the magnetic field remains.

Inductor working diagram

Whereas the magnetic field is made as long as you give the power to the inductor. If you stop giving power to the inductor, then the power remains stored for about half a second. So there is a benefit in that, when the power is repeatedly turned on and off, then we put it in the middle of the circuit, then the power will go continuously continuously, that is, the power that goes ahead will not be turned on and off again and again.

How inductors can give constant current :

This is the main job of the inductor to forward the current by constipating it and how it gives the constant current. First, when you connect the battery and the bulb, then connect the inductor, then the current goes from the battery to the first inductor, a magnetic field is formed in it, only after the magnetic field is formed does the current accumulate in it. In the current bulb. The bulb starts to wake up after the current. This is the first step that completes, after this, when you turn the battery off and on again, the bulb will not turn off, it will continue continuously because when you stopped sending current from your battery then the current which was stored in that inductor was the current bulb. I went in due to which the bulb was awakened. As soon as the current starts to finish, in the same time in that inductor, you turn on the current from the battery again, due to which current starts to accumulate from the inductor and the bulb wakes continuously.

The current from the DC generator is turned on and off several times causing the bulb to turn on and off. Sometimes, the bus is mounted continuously to wake the bulb in the middle so that the bulb or any device can run continuously.

How inductors are made :

Making an inductor is not a very difficult task but an easy task as it has very few parts. Copper wire and rod are mainly used in this. So how it is made according to the picture, we know ahead.

How inductors are made

In this, the copper wire is first wrapped in one place. When the copper wire is wrapped and taken out, it is called an inductor. Some inductors are such that there is an iron or some other metal rod in the middle. To make it, the copper wire is wrapped and left over the rod. This is how the inductor gets ready.

How much value will be in the inductor depends on the turn of the copper wire. Inductors come in different values. All those inductors would have differentiated the turn of that wire and the rod used between it.

One thing you must always keep in mind is that the more the copper wire turns, the more well it helps to constrain the inductor in the inductor. How much value of an inductor should be applied in the circuit depends on the power going over that circuit.

Use of inductor :

We have explained below about the devices where the inductor is used, which is as follows:

Delivered constant current :

Inductors are used in devices that do not have continuous electrical current and require more voltage. It is necessary to install inductors such as powerbanks, induction cookers, televisions, printers, etc. to operate the devices continuously. There are many devices in which inductors are used.

Increases voltage :

Some devices require higher voltages such as the voltage of all the batteries inside the power bank, ranging from 3.4 volts to 4.2 volts whereas the smartphone requires 5 volts to charge. So it also has an inductor placed inside the power bank which increases the voltage by which we can charge the smartphone.

In wireless systems :

It is now used in today's wireless systems such as inductors are also used in the charger charging the smartphone, so that we can easily charge the smartphone without charging any wires. But it is charged only when you take the smartphone very close to the charger. Because it is possible to transfer power only after the arrival of another device under its magnetic field.

Used in remote controller :

Also it is used in remote control to send signals to far distance. In the remote control, the signal reaches the receiver or equipment only after pressing the button, after which we can control the device through the remote.

Advantages of inductor :

1. Constant sends the power forward.
2. This inductor is the work of increasing the voltage.
3. It stores very small amount of power with the help of magnetic field inside itself.
4. This inductor is useful even when the equipment is running at high voltage.
5. It is also used extensively in wireless devices.
6. This inductor transmits power from one circuit to another without any wires, also known as wireless chargers.
7. With this help, we can make new technology devices such as wireless technology.
8. By far it is capable of sending inductor signals.

Disadvantages of inductor :

1. The biggest drawback of inductors is that it does not work on ac current.
2. Power transfer with the help of inductor leads to some amount of electrical waste leading to higher power consumption.
