Assertion: Soft iron is used as transformer core.
Reason: Soft iron has narrow hysteresis loop.

A

If both asseration and reason are true and reason is the correct explanation of assertion.

B

If both asseration and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Hysteresis loss in the core of transformer directly proportional to the hysteresis loop area, that is why soft iron core is used in the transformer.
