What is the main function of a transformer's core?
A
To generate voltage
B
To store electrical energy
C
To resist current flow
D
To provide a path for magnetic flux
Correct Answer: Option D — To provide a path for magnetic flux
Explanation:
A transformer's core, typically made of laminated iron, provides a low-reluctance path for magnetic flux generated by the primary coil. This efficiently channels the flux to the secondary coil, minimizing energy losses and enabling effective voltage transformation.
