Assertion : An ideal transformer does no...

Assertion : An ideal transformer does not vary the power.
Reason : An transformer is used to step-up or step-down ac voltages.

A

If both assertion ans reason are true ans reaason is the correct explanation of assertion.

B

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

C

If assertion istrue but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
By using transformer voltage can be be increased or decreased. An ideal transformer is one in which there is no energy loss. If there is no loss of energy then the entire input power is transferred from the primary to the secondary i.e. output.
