What is a transformer?

A power transformer is a static electrical device that converts a certain value of AC voltage (current) into another or several different values ​​of voltage (current) with the same frequency a static device with two or more windings that converts the AC voltage and current of one system into the voltage and current of another system at the same frequency through electromagnetic induction in order to transmit electrical energy. Usually, the values ​​of these currents and voltages are different.
