 What is Transformer:-

Transformer is Static Device that transfers electrical energy from one electrical circuit to another electrical circuit. Transformer works on Principle of Mutual induction

Stage down and stages up the voltage and also  the level of current with less or less. Transformer is an AC device without frequency

The level step of the voltage is changed by sub-station or downstream transformer was invented by Michael Faraday or Joseph Henry in 1831, which is called transformer

Working Principle of transformer -;

Uses Faraday’s electromagnetic induction Rule to work for An electrical transformer  – “Rate of change of flux linkage with respect to time is directly proportional to the induced EMF in a conductor or coil”.

 A transformer’s physical basis lies in the mutual induction between two circuits that are linked by a common magnetic flux. It is usually equipped with 2 winding: primary and secondary. These winding share a magnetic core that is laminated, and the mutual induction that takes place between these circuits helps transfer electricity from one point to another.

What is Transformer 

 The  important Material of an electrical transformer are  primary winding, and secondary winding and  magnetic core, . The primary winding is  connected to an electrical supply , from where magnetic flux is initially produced. These coils are insulated from each other and the main flux is induced in the primary winding from where it is passed to the magnetic core and linked to and through the low reluctance path of transformer’s secondary winding 

The core relays the flux to the secondary winding to create a magnetic circuit that closes the flux, and a low reluctance path is placed within the core to maximize flux linkage. The secondary winding helps complete the movement of the flux that begins at the primary side, and using the core reaches the secondary winding. The secondary winding is able to pick momentum because both winding are wound on the same core and hence their magnetic fields help to create motion. In all the types of transformers, the magnetic core is assembled by stacking laminated steel sheets leaving the minimum required air-gap between them to ensure the continuity of the magnetic path.

Construction of Transformer -:

 Electrical transformers are machines that transfer power from one electrical circuit to another electrical circuit  with changing voltage level but no frequency change. present time, they are designed to use AC supply, that means that fluctuation in supply voltage is impacted by the fluctuation in the current. So, an increase in current will bring about an increase in the voltage and vice versa.

Transformer is two winding (primary and secondary) and a laminated iron core is the function of the iron core in the transformer, the principle is to provide the path of low reluctance to the magnetic flux

If we have an ac supply, we can lend the iron core to reduce the losses, then the silicon steel material is used for laminate. The quantity of side silicon steel is high
