The core of a transformer is laminated because:

The core of a transformer is laminated because:
  1. ratio of voltage in primary and secondary may be increased
  2. energy losses due to eddy currents may be minimised
  3. the weight of the transformer may be reduced
  4. rusting of the core may be prevented

Solution

The core of a transformers is laminated to minimise the energy losses due to eddy currents.
