Find current, phase difference, potential and average power used in a pure inductive AC circuit. Also draw phasor diagram.

In an $\mathrm{AC}$ circuit with all components connected in series, the emf and the current are given by

$\mathrm{V}=200 \sin \left(314\mathrm{t}+\frac{\mathrm{\pi }}{6}\right)$ volt and $\mathrm{I}=5 \sin 314 \mathrm{t}$ ampere obtain (iii) the phase difference between $\mathrm{V}$ and $\mathrm{I}$.
