What are the two sides of a transformer called?

The two sides of a transformer are referred to as the primary and secondary. The primary side is where the input voltage is applied, causing a magnetic field to be generated around the coil. This magnetic field is then transferred to the secondary side, where it induces a current and voltage that can be higher or lower than the primary side, depending on the transformer’s design and turns ratio.

Understanding the terms primary and secondary is crucial, as they reflect the function of each side within the context of electricity transformation. The primary winding is responsible for the input, while the secondary winding reflects the transformed output that can be utilized for various applications.

The other choices do contain relevant information about transformers but do not accurately designate the standard terminology. For instance, the input and output terminology is more generic and can apply to various electrical devices, while high voltage and low voltage refer specifically to the voltage levels and not the specific sides of the transformer. Similarly, the terms transformer and load do not correspond to the sides of the transformer; rather, the load refers to the device that uses the transformed electrical output.
