How Transformers Manage Electric Current

Basic Operating Principle

Transformadores operate on Faraday’s law of electromagnetic induction, transferring electrical energy between circuits through magnetic coupling. When alternatingatual flows through the primary winding, it creates a changing magnetic field that induces a voltage in the secondary winding. This process allowstransformadores to increase or decrease voltage levels while inversely affecting theatual – higher voltage means loweratual and vice versa.
