This is the transformer of electricity. We have a small factory next to our house. The factory owner bought three of these transformers for his factory. The electricians have installed these on the cement poles. We often see these transformers in different areas. Today I will tell you how this transformer works. 😱 First I will tell you what is a transformer? A transformer is a stationary electrical device by which a certain amount of electrical energy at an unchanged frequency in an alternating electrical system can be transferred from one circuit to another by increasing or decreasing the voltage according to the value. These transformers are made of cast iron with copper wrapped inside. This transformer is attached to the pole with a separate angle.
