Statement I: The alternating current lags behind the emf by a phase angle of 
, when AC flows through an inductor.
Statement II: The inductive reactance increases as the frequency of AC source decreases.
In the light of the above statements, choose the most appropriate answer from the options given below.
Text Solution
Verified by ExpertsB
Statement I is correct but Statement II is incorrect.
When pure inductor is connected to source of an alternating emf, then instantaneous value of alternating emf is given by 
, and corresponding alternating current is given by 
. From these two equations it follows that alternating current lags behind emf by a phase angle of 
. The inductive reactance, 
, so when frequency increases correspondingly inductive.
