What is a transformer? Best information

What is Transformer: Hello friends, you are warmly welcome in today’s article full of information, friends, you all know how much electricity is important in our lives, if there is no electricity in our daily life, then do any work. It becomes difficult, even today every single material runs on electricity, but have you ever wondered where this electricity comes from and controls it at a controlled angle?

There are many devices in the world and they also have different technical knowledge to operate, but there is also such a device that if we do not live in our world, then we may never have electricity, and the name of that device is What is a transformer.

Now what is this Transformer and what is its use, you will know in full detail in today’s article, and I will also tell you how you can make your own What is a transformer in your own home, so read this article carefully.

Why are transformers used?

If you also have this question in your mind that why do we need a Transformer at all? So in answer to this, I would like to say that in today’s time, the electricity you are using in your house or in any place, there is a direct payment of Transformer in providing it.

If the transformer is not there, then all the electrical materials in your house will be finished in an instant, it is the transformer that always controls the electricity in the same way, due to the transformer, the electricity coming to the houses will never decrease or There is not much quantity, so by controlling the amount of electricity, we need a Transformer to get a precise amount of electricity.

What are the types of transformers?

Actually, only 2 types of Transformer are available, whether it is electrical or electronic, the same type of transformer is seen everywhere, whose name is Step-Up Transformer and the other is Step-Down transformer, in both the work. So it is the same to control the current electricity, but both are used for different tasks, and the work of both is different, so let’s know what is the difference between the two transformers and how they work.

Step Up Transformer

It is used to increase any current, whichever transformer provides further voltage after increasing it is called Step Up transformer, its composition is core type or shell type.

The windings of the step up transformer are more secondary than the primary turn. Due to this, the flux of the primary is cut more than that of the secondary. And as a result, due to the action of mutual induction in the secondary winding, more voltage is created. And the higher the voltage of the primary winding, the lower the current of the secondary.

Now the question is, where is the Step Up Transformer used because we are seeing in our homes that the voltage we get by reducing the excess voltage is 230V, so after all this Step Up transformer is used. Where is it done?

So friends, Step Up Transformer is used in many places, if it is not there, then probably many appliances in your homes will not be able to work, TVs or any equipment in your homes in which this Step Up transformer was used. It goes, for example, the TV present in your house.

There is many times more light inside the TV and this light cannot be layered by an ordinary LED, and that is why high power LED is used, and it needs high power to run.

But the voltage in our house is only 230V, to convert it into more power, Step Up Transformer is required, sometimes our TV runs only on 12V or 24V, because it lowers the electricity bill. , but the LED inside it runs with more power, and any voltage can be added to the step-up transformer.

In the same way, the train also runs on electricity, but you all know that if the distance is more then due to the resistance of the wire, that power gradually starts decreasing, and to provide regular power to the train, many Step Up transformer is used in place, apart from this Step Up transformer is used in many places so that electricity can reach in every area.

Step Down Transformer

Now I think you must have come to know about this, but our task is to reach the information to you, because some people are so stupid that they have to explain everything in detail, so let’s know that the use of Step Down Transformer Where is it done and how does it work.

So understand in simple language, where there is a need to reduce the voltage, there is a need for a Step Down Transformer, such as the electricity coming to your house, the Step-Down Transformer installed near your house, first in it. 11000V is given, and the Step Down Transformer reduces it to give you 230V.

Now the question may also be that if we need only 220V then why do we reduce 11000V? Why can’t get 220voltage directly? [What is a transformer]

So my dear friend, if we will produce 230voltage directly, then it will be converted into 10 voltage by the time it reaches your home, because there is no manure of your father, from where electricity is generated daily, nor can it be done in your house. can do.

Therefore, the greater the distance, the more current will be consumed, and this is not the case, so 11000 voltage is delivered to your home, and after reducing it, the same amount is injected into your dirt, which you use to charge the mobile and Shake your ass on Instagram.

Moreover, the Step Down Transformer is also used inside the charger of your mobile, so that 230voltage can be reduced to 5V and it can charge your mobile.

If this does not happen, then the current will directly feel to you that the mobile will explode, and you will keep shouting waxy, and you will never feel like touching Instagram in life, people of Bhosdi. [What is a transformer]

Transformer Winding

It is very simple, there are 2 types of coil in any transformer, one is primary and the other is secondary, and both have coils, but in different quantities, as you can see in the above image that both The star is depicted as a coil, but one is thin and the other is thick.

Now out of these, the one shown as primary inputs the current, that is, the supply is given in it, and the second is called out put, in which the current is received, now for each task, a different number of coils are winded. Is. [What is a transformer]

The question in everyone’s empty mind will also be whether both the windings are connected to each other? So my dear samples is not like this, if this happens then the current can never be controlled, both the windings are kept on top of each other, and when the current passes over the in coil then the second winding according to its capacity. It catches some voltage from it and starts flowing further, this winding is done by compressing it so much that tremendous magnetic power is generated inside it, and due to this reason you can get the current even further.

How does a transformer work?

When AC current is supplied to the required winding of the transformer. Then, at that point, changing the attractive lines corresponds to the required windings. They cut through the fixed guides due to changing attractive lines.

Also, a self-actuated EMF is created in the essential winding. AC current moves through the required winding, causing a variable transition around the required winding.

The required speed passes through the center and reaches the secondary winding. The normally induced emf is created in the auxiliary winding by making a cutting move between the turns of the transition and alternating windings.

According to Ferred’s second law of electromagnetic enlistment, the emf created is relative to the turns of the windings. Meaning, the more turns in the winding, the greater the cutting activity, the more stable the EMF is created.

At the point when the alternating winding is connected with the stack, the auxiliary circuit is terminated and current is beginning to flow through the winding. What’s more, electrical power is given to the stack as a result. This is how the transformer works.

What is the difference between core type transformer and shell type transformer?

Core Type TransformerShell type Transformer
There is only one way for the flux to flow.
Winding takes place on the limb on the days of the core.
Since the winding is on the outside, it helps to keep the winding cool from outside air.
The average length of the core is more.
The area of ​​the hole cut across the core is less.
Leakage flux proof is low.
The winding being on the outer limb is easily visible, and easy to maintain.
It is suitable for high voltage.
There are two routes for the flux to flow.
There is a winding on the middle limb.
The core is cooled because the winding is at the middle limb.
The average length of the core is short.
The area of ​​the hole cut across the core is more. Hence there are fewer turns.
Evidence of leakage flux is high.
Difficult to repair. And winding was not easy.
Suitable for low voltage.

How to make transformer at home?

So the virtuous souls present in this earth, if you also want to make a transformer in your own home, then you can definitely do so, but for this you need knowledge, and knowledge is filled in this article of ours, that’s why we like you It is being told, read it carefully.

  • First of all you need an iron blade, it would be better if you buy L or E, blade to make a transformer from a shop, and if there is no money then you can work with any iron blade.
  • Now you need Copper wire, you have to buy it.
  • After this you have to wrap 120 rounds of wire over that iron, this will be the primary coil of your transformer.
  • And now you have to push the coil with the help of an insulated paper.
  • And now you have to rotate 500 rounds again over the same coil, but this wire should be thinner than the first wire.
  • And this will be your secondary coil, and also push it with the help of insulated paper.
  • Now you have to connect the current supply in the first coil, as a result, you will find that there is some voltage layer happening from your secondary coil, and this will be DC voltage.
  • Just in this way you can make a simple transformer at home, but it is only for learning, if you want to make a transformer for someone, then you have to buy the right material from the shop.

Why is a transformer called a stationary device?

This is because the transformer works according to the Self or Mutual Induction element of Electro Magnetic Induction, that is, other equipment such as a motor or other magnetic device starts rotating to work, but a transformer always remains stationary, and by creating a magnetic field. Works, that’s why transformer is called stationary device, because it is stationary, means it does everything secretly and you do not even know. [What is a transformer]

What is the principle of transformer?

The transformer works according to the Self or Mutual Induction element of Electro Magnetic Induction.

Means when another coil is kept stationary in a changing magnetic field. Then those changing magnetic lines get cut due to the conductor of the coil kept stationary. And because of this, EMF is created in the coil kept stationary according to Ferede’s Element of Electro Magnetic Induction.

What is a transformer made of?

Generally, a transformer is made of iron, chosen soil, or wire (Copper, Aluminum), but some transformers which are used in the existing appliances at home, plastic is also seen in them.

What is the function of the transformer?

The function of a transformer is to increase or decrease the current, different types of transformers are made for different work, about which we have told you.


So friends, in today’s article, we talked about What is a transformer and taught how a transformer works, and I have also used some such words which you might not like, if so, then definitely contact us. We will try to remove it, and if you liked this article, then do share it with your friends.
