Introduction to Transformers

The video explains the function and structure of transformers, which are devices used to adjust the voltage of alternating current. Transformers are found on telephone poles and in electronic devices. Step-down transformers reduce high voltage to a safer level for home use, while step-up transformers increase voltage for devices like televisions. The video details the components of transformers, including primary and secondary coils, and explains electromagnetic induction.
