What is the term used to describe the output side of a transformer?

The term used to describe the output side of a transformer is the secondary side. In transformer terminology, the primary side refers to the input winding, which is connected to the power source. The secondary side, on the other hand, is where the transformed voltage and current are delivered for use in a load. This arrangement works based on the principle of electromagnetic induction, where the primary winding generates a magnetic field, and the secondary winding captures that energy to produce an output voltage.

Understanding the roles of the primary and secondary sides is crucial for grasping how transformers function in electrical circuits, including their applications in stepping up or stepping down voltage levels. This differentiation is fundamental to electrical engineering and helps in designing and implementing systems that rely on transformers for energy transmission and distribution.
