How many Types of Transformers are there?

Answer:- Transformers are commonly used electrical devices based on the principle of electromagnetism. Based on the level of voltage, a transformer can be categorised into the step-up transformer, step-down transformer and isolation transformer. The other types of transformers based on the core material can be an iron core transformer, ferrite core transformer, air core transformer and toroidal core transformer. Another type of transformer can be an auto winding transformer, that is, based on the wiring arrangement of transformers. Thus, there are many different types of transformers based on various parameters such as their function, wiring arrangement and construction.
