Question

Assertion : A step-up transformer changes a low voltage into a high voltage.
Reason : This violate the law of conservation of energy.
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.

Correct Answer - C
A step up transformer changes a low voltage into a voltage. This does not violate the law of conservation of energy, because the current is reduced by the same proportion.
