Assertion : The alternating current lags behind the e.m.f. by a phase angle of $\pi / 2$, when AC flows through an inductor. Reason : The inductive reactance increases as the frequency of AC source decreases.

Question

Assertion : The alternating current lags behind the e.m.f. by a phase angle of $\pi / 2$, when AC flows through an inductor. Reason : The inductive reactance increases as the frequency of AC source decreases., If both assertion and reason are true and reason is the correct explanation of assertion, If both assertion and reason are true but reason is not the correct explanation of assertion, If assertion is true but reason is false, If both assertion and reason are false.

MARKS App · Accepted Answer

Assertion is correct but reason is false because inductance reactance X L ​ = 2 π f L . So, higher frequency greater inductance reactance.
