ELECTRICAL TRANSFORMER
An electrical transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

Function: They step up (increase) or step down (decrease) voltage levels while maintaining the same frequency.
Components: Consist of primary and secondary windings (coils) and a core, which is typically made of iron or steel.
Working Principle: Operates on the principle of mutual induction where a changing current in the primary winding creates a changing magnetic field, which induces a current in the secondary winding.
Types: Includes power transformers, distribution transformers, isolation transformers, instrument transformers, and more.
Applications: Widely used in electrical power distribution and transmission systems, in electronic devices for voltage regulation, and in various industrial applications.
