Transformers

The video explains transformers, devices that change the voltage of an alternating current. It covers how transformers work, including their components like primary and secondary coils, and the role of alternating current. The video distinguishes between step up and step down transformers, explaining how they alter voltage levels. It provides a calculation example to determine the voltage in a secondary coil. The video also discusses the real-world application of transformers in electricity transmission, highlighting the importance of high voltage for efficient power transfer and the need for step down transformers for safety in homes.
