The three main types of transformers are:
1. **Step-up Transformer**: This type increases the voltage from the primary side to the secondary side. It is used when you need to raise the voltage, for example, in power transmission to minimize energy loss over long distances.
2. **Step-down Transformer**: This type decreases the voltage from the primary side to the secondary side. It is used when you need to lower the voltage, such as for supplying power to homes or small devices.
3. **Isolation Transformer**: This transformer is used to isolate two circuits. It doesn't change the voltage (the primary and secondary voltage are the same), but it separates the two circuits for safety, noise reduction, or grounding purposes.
Each type serves a specific function depending on the application and the desired outcome in terms of voltage change.
