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.
