A transformer is a device designed to modify the voltage and electric current levels, keeping electrical power practically constant, from one circuit to another, also modifying the electrical impedance values of an electrical circuit.
Invented in 1831 by Michael Faraday, transformers are devices that work by inducing current according to the principles of electromagnetism, that is, it works based on the electromagnetic principles of the Faraday-Neumann-Lenz Law and the Lenz Law, where it is stated that it is possible to create an electrical current in a circuit once it is subjected to a variable magnetic field, and it is because of the need for this variation in the magnetic flux that transformers only operate in alternating current.
