Question

Assertion (A): Lenz's law is a consequence of the law of conservation of energy.
Reason (R): There is no power loss in an ideal inductor.

• A. Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
• B. Both Assertion (A) and Reason (R) are true, but Reason (R) is not the correct explanation of the Assertion (A).
• C. Assertion (A) is true, but Reason (R) is false.
• D. Assertion (A) is false and Reason (R) is also false.

Hint:

Lenz’s law follows the principle of conservation of energy, while an ideal inductor stores energy without dissipation, making both statements true but unrelated in explanation.

Answer 1

The Correct Option is B

Lenz’s law is a consequence of the conservation of energy, as it ensures that the induced current always flows in a direction that opposes the change in magnetic flux. The statement that there is no power loss in an ideal inductor is also true because an ideal inductor does not dissipate energy; instead, it stores energy in the magnetic field. However, this does not directly explain Lenz’s law, making option (2) the correct choice.
