What is the primary function of the secondary winding in a transformer?

The primary function of the secondary winding in a transformer is to supply energy to the load device. In a transformer, there are two windings: the primary winding, which connects to the input voltage source, and the secondary winding, which is where the output voltage is taken and supplied to the load. When alternating current flows through the primary winding, it creates a magnetic field that induces a voltage in the secondary winding through the process of electromagnetic induction. The voltage in the secondary winding can either step up or step down the voltage depending on the turns ratio of the transformer. Consequently, the secondary winding is essential for transferring the electrical energy from the transformer to the device or circuit it is powering. It is specific to the design of the transformer and reflects its role in energy distribution within electrical systems.
