0Instantaneous values of current and e.m.f. in an \( \mathrm{AC} \) circuit are \( I=1 / \sqrt{2} \sin (314 t) \mathrm{A} \) and \( E=\sqrt{2} \sin (314 t-\pi / 6) \mathrm{V} \) respectively. The phase difference between \( E \) and \( I \) relative to current will be
(A) \( \pi / 3 \mathrm{rad} \)
(B) \( -\pi / 3 \mathrm{rad} \)
(C) \( \pi / 6 \mathrm{rad} \)
(D) \( -\pi 6 \mathrm{rad} \)
