Transformer
Transformer is the basic element that transfers energy in one circuit to the other circuit through electromagnetic induction. They are generally used in electric power applications to increase or decrease the voltage of AC current.

Iron Core
Uses a piece of magnetic material as core. Generally Ferro magnetic metals like iron are used. The core has high permeability and is used to confine the magnetic field.

|
Center Tapped
The center tapped transformer has its secondary winding divided into two parts with same number of turns in each part. This results in two individual output voltages across two line ends. Used in rectifier circuits.

|
Step Up Transformer
The no. of turns in secondary winding is more than that of primary winding. The output voltage is higher than input voltage. Significantly used in inverters.
|
|
Step Down Transformer
The no. of turns in secondary winding is less than that of primary winding. The output voltage is lesser than input voltage. It is widely used in low power applications.
