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 in electrical power transmission and distribution systems.
There are two main types of transformers: step-up transformers, which increase voltage, and step-down transformers, which decrease voltage.
Other types of transformers include autotransformers, isolation transformers, and instrument transformers.
Transformers are commonly used in various applications such as power generation, industrial machinery, and electronic devices.
Example: A step-down transformer is used to reduce the high voltage from power lines to a lower voltage suitable for household use.
