Step Up and Step Down Transformers: Understanding the Differences

This video tutorial explains the differences between step up and step down transformers. It begins with an overview of transformers, which are devices that modify the potential difference of an alternating current supply. The video then details the characteristics of step up transformers, which increase potential difference, and step down transformers, which decrease it. The tutorial further explores the turns ratio equation and how it relates to the potential differences across the primary and secondary coils in both types of transformers.

What is the primary function of a transformer?

Describe the difference in the number of turns between the primary and secondary coils in a step up transformer.

Explain the relationship between the number of turns on the coils and the potential difference in transformers.

How does the potential difference across the secondary coil of a step up transformer compare to that of the primary coil?

What happens to the potential difference in a step down transformer compared to a step up transformer?
