In the shown AC circuit phase difference between
\( P \)
currents \( I_{1} \) and \( I_{2} \) is
(1) \( \frac{\pi}{2}-\tan ^{-1} \frac{x_{L}}{R} \)
(2) \( \tan ^{-1} \frac{x_{L}-x_{C}}{R} \)
(3) \( \frac{\pi}{2}+\tan ^{-1} \frac{x_{L}}{R} \)
(4) \( \tan ^{-1} \frac{x_{\mathrm{L}}-x_{\mathrm{C}}}{R}+\frac{\pi}{2} \)
