What is the primary use of an iron core step down transformer?

The primary use of an iron core step-down transformer is to reduce voltage. This type of transformer takes an input voltage at a higher level and transforms it to a lower output voltage. The iron core enhances the efficiency of the transformer by providing a path for the magnetic flux, which enables better coupling between the primary and secondary windings. As a result, when alternating current (AC) flows through the primary coil, it creates a varying magnetic field that induces a lower voltage in the secondary coil. This reduction is beneficial in applications where lower voltage levels are needed for safety and compatibility with devices that cannot operate at higher voltage levels. This is particularly important in residential and commercial settings, where devices require low voltages to function safely and effectively.
