Transformer working principle and uses in electrical engineering field


A transformer with a constant value that exceeds and reduces the value of AC voltage by mutual induction without altering the frequency is called a transformer.

After the generation of electricity, the way it is up and down is reached in far-flung areas according to its requirement. It is not possible without a transformer.
 
Transformers do not have a frequency change. The frequency that remains in the input is in the output. Its main function is to step up and step down any voltage level.

No part is missing in this type of creation. It is a static device that works only in AC supplies. The transformer does not work in DC supply.
