Step 1
Suggest why the transformer can be adjusted to have different numbers of turns on the secondary coil.
Answer
The transformer can be adjusted to have different numbers of turns on the secondary coil to vary the output potential difference. This allows for compatibility with devices that require different potential differences, ensuring that multiple types of devices can be powered without needing different generators.
