Assertion: When a ferromagnetic rod is i...

Assertion: When a ferromagnetic rod is inserted inside an inductor, then current in L-C-R, alternating circuit will decrease.
Reason: By inserting the ferromagnetic rod inside the inductor, coefficient of self induction and hence the net impedance will increases.

A

(a) If both Assertion and Reason are true and Reason is the correct explanation of Assertion.

B

(b) If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.

C

(c) If Assertion is true but Reason is false.

D

(d) If both Assertion and Reason are false.

e) `Z=sqrt(R^(2)+(X_(L)-X_(C))^(2))`
By inserting the ferromagnetic rod L, and therefore `X_(L)` will increase. But value of Z and therefore I may increase, decrease or remain same.
