What is transformer and explain types of transformer ?

Question

Accepted Answer

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.

Transformers are used to increase or decrease the voltage levels in electrical power transmission and distribution systems.
There are two main types of transformers: step-up transformers and step-down transformers.
Step-up transformers increase the voltage level, while step-down transformers decrease the voltage level.
Other types of transformers include autotransformers, isolation transformers, and instrument transformers.
Autotransformers have a single winding that acts as both the primary and secondary winding.
Isolation transformers are used to provide electrical isolation between the input and output circuits.
Instrument transformers are used to measure current or voltage in high voltage systems.

Accepted Answer

Transformers is a static device, Transfers electrical energy from one circuit to another without any changes in frequency, transformer works on the principal of mutual induction.

Transformers basically two types -

Step down
Step up

Transformers are many type they depends on there structure
