Assertion: The resistance offered by an inductor in a d.c. circuit is always constant. Reason: The resistance of inductor in steady state is non-zero.
1 If both Assertion and Reason are correct and reason is the correct explanation of the Assertion.
2 If both Assertion and Reason are correct, but the Reason is not the correct explanation of the Assertion
3 If Assertion is correct but Reason is incorrect
4 If both the Assertion and Reason are incorrect
Explanation:
D Resistance offered by an inductor in a d.c. circuit at is infinity, which decreases to zero at steady current. Hence, both the assertion and reason incorrect.
