The main type of transformer is typically called the **"power transformer"**. It's used to transfer electrical energy between two circuits through electromagnetic induction, usually to step up (increase) or step down (decrease) voltage levels in power transmission and distribution systems.
Other common transformer types include:
1. **Distribution transformers** – These are used to provide power to homes and businesses by stepping down voltage.
2. **Isolation transformers** – Used to isolate two circuits for safety, preventing electrical noise or interference.
3. **Autotransformers** – A transformer with a single winding that acts as both primary and secondary, typically used for voltage regulation.
