  1. In and ideal transformer on no load, the primary applied voltage is balanced by the secondary.
  2. The concentric windings are used in core type transformer with LT winding placed next to core.
  3. Cross over windings are used for high voltage winding of small rating transformers.
  4. The magnitude of mutual flux in a transformer is same at all levels.
  5. The induced emf in the transformer secondary will depend upon frequency, flux and number of turns in the secondary.
