Question

Assertion :The inductive reactance limits amplitude of the current in a purely inductive circuit Reason: The inductive reactance is independent of the frequency of the current

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is C Assertion is correct but Reason is incorrect

$z=\sqrt{R^2+X_L^2}$

where $X_L=wL$

Also, $I=\frac{V_0}{Z}\sin \left(wt\right)$

Thus as value of $L$ changes, $z$ changes and thus amplitude of $I$, ie $\frac{V_0}{z}$ changes
