The core of a transformer is laminated to: Correct Answer Reduce the power loss due to eddy current

CONCEPT:

  • Transformer: It is a device used in the power transmission of energy.
    • It works on the principle of mutual induction, where two coils are coupled, namely the primary and the secondary coil.
    • The primary coil creates a varying magnetic flux, which in turn induces an EMF on the secondary coil.
    • If the number of windings on the primary coil is greater than the secondary windings, then it is called a step-down transformer.
    • If this case is vice versa then the transformer is a step-up transformer.

Important Points

  • The efficiency of the transformer depends on how well the input power is transferred as output power.
  • Thus to increase the efficiency, the windings of the coil must be increased and magnetic flux leakage must be reduced.
