Phase Difference in AC Circuits – Rankers Physics

LR, RC and LCR Circuits: Practice Problem & Solution

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

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of LR, RC and LCR Circuits. Understanding the underlying formula is key to arriving at the correct answer below:

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.
