Phase Difference in AC Circuits

Statement A: In a pure capacitive ac circuit, the phase difference between current and voltage is \(\pi/2\).
Statement B: In a pure inductive ac circuit, the phase difference between current and voltage is \(\pi\).
 
Both statement (A) and statement (B) are correct
Both statement (A) and statement (B) are incorrect
Statement (A) is correct and statement (B) is incorrect
Statement (A) is incorrect and statement (B) is correct

Solution:

In a purely capacitive circuit, current leads the voltage by \(\pi/2\). In a purely inductive circuit, current lags the voltage by \(\pi/2\). Hence, Statement A is correct while Statement B is incorrect.
