| Assertion: An inductor acts as a perfect conductor for D.C. |
| Reason: D.C. remains constant in magnitude and direction. |
A) If both assertion and reason are true and reason is the correct explanation of assertion.
B) If both assertion and reason are true and reason is not the correct explanation of assertion.
C) If assertion is true but reason is false.
D) If both assertion and reason are false.
E) If assertion is false but reason is true.
Correct Answer: B
Solution :
The frequency of D.C. is equal to zero. The inductive reactance of inductor is \[{{X}_{L}}={{\omega }_{L}}=2{{\pi }_{f}}L\]. Therefore when D.C. is applied across inductor, it offers zero inductive reactance to the source and act as perfect Conductor for D.C.
