i may sound dumb, but what is a transformer, its purpose, and what kind of transformer are you using?

A transformer is an electrical component that has two sides (a primary and a secondary). It is used to step a voltage up or down according to the need. His transformer takes the 120 volts AC (alternating current) from the outlet into the primary side and steps it down to 9 volts on the secondary while also converting it to DC (direct current) by additional methods.
