What is the role of secondary windings in a transformer?

The role of secondary windings in a transformer is to transform voltage for use. In a transformer, the primary winding receives the input voltage, and through the process of electromagnetic induction, this voltage is transformed when it induces a magnetic field in the core which then interacts with the secondary winding. The number of turns in the secondary winding compared to the primary determines whether the voltage is stepped up or stepped down.

When the secondary winding is designed properly, it allows the electrical energy to be utilized at a different voltage level suited for various applications. This transformation is essential in power distribution systems, where it is necessary to adjust voltages for safe and efficient transmission and usage. Thus, the secondary winding effectively serves to adapt the voltage levels for the end-user or subsequent stages in the electrical circuit.

The focus of the secondary winding on transforming voltage directly ties into the functionality of the entire transformer, allowing for the safe and effective distribution of electrical power across different devices and systems.
