What is the function of a step down transformer?

A step down transformer is specifically designed to reduce the voltage from a higher level to a lower level. This is achieved through its windings: the primary winding has more turns than the secondary winding, which results in a decrease of voltage when alternating current (AC) passes through it. This function is particularly important in electrical systems where it is necessary to convert high transmission voltages into lower voltages suitable for use in residential or commercial applications, making it a crucial component in power distribution.

The application of step down transformers can be seen in various settings, such as energy distribution networks where electricity is transmitted over long distances at high voltages to minimize losses, and then stepped down for safe usage in homes and businesses. Understanding the role of a step down transformer is fundamental for anyone working in electrical systems or studying electrical engineering.
