Electrical Components Detection for Transformers

Mar 20, 2021Now we will learn about the important parts of a transformer. Parts of a Transformer. A transformer is built from many different parts with their specific functions to make sure it works very well. If we have learned or read about a transformer we will remember that a transformer is built from: core, primary winding, and secondary winding.
