The purpose of providing an iron core in a transformer is to
A. provide support to windings
B. reduce hysteresis loss
C. decrease the reluctance of the magnetic path
D. reduce eddy current losses
Answer: Option C
Solution(By Examveda Team)
The purpose of providing an iron core in a transformer is to decrease the reluctance of the magnetic path.The iron core is used to improve the efficiency of the transformer by providing a low reluctance path for the magnetic flux. This allows the transformer to transfer electrical energy more effectively between its windings.
Key Points:
Iron Core: Reduces the reluctance (magnetic resistance) of the magnetic path, enhancing the transformer's efficiency.
Reluctance: The resistance to the flow of magnetic flux. By decreasing reluctance, the core helps in better flux linkage between the primary and secondary windings.
This Question Belongs to Electrical Engineering >> Transformers
to pass same flux from primary side to the secondary winding which was wounded on the common magnetic core should have low reluctance
It also decrease hysteresis loss
