    1. What is a power transformer?

    Ans: A power transformer is an electrical device that transfers electrical energy between different voltage levels. It consists of primary and secondary windings wound around a core and is used to step up or step down voltage for efficient transmission and distribution of electricity.

    2. How does a power transformer work?

    Ans: A power transformer works on the principle of electromagnetic induction. When an alternating current flows through the primary winding, it creates a changing magnetic field in the core. This changing magnetic field induces a voltage in the secondary winding, leading to voltage transformation.

    3. What are the types of power transformers?

    Ans: There are several types of power transformers, including distribution transformers, power transformers, autotransformers, instrument transformers, and specialty transformers for specific applications.
