Given below are two statements: Statement-I: In an a.c. circuit containing only a pure inductor, the alternating current leads the alternating voltage by a phase angle of 2 . Statement-II: The opposition offered by a pure inductor to the flow of alternating current increases with an increase in the frequency of the a.c. source. In the light of the above statements, choose the most appropriate answer from the options

Step-by-step solution

In an a.c. circuit containing only a pure inductor, the alternating voltage leads the alternating current by a phase angle of 2 , which means the current lags the voltage by 2 . Thus, Statement-I is incorrect. The opposition offered by a pure inductor to the flow of alternating current is called inductive reactance, given by X_L = L = 2 f L . As the frequency f of the a.c. source increases, the inductive reactance X_L also increases. Thus, Statement-II is correct. Answer: Statement-I is incorrect but Statement-II i
