In an ac circuit, the instantaneous values of current (in A) and voltage (in V ) are $\displaystyle \mathrm{I}=5 \sin \omega \mathrm{t}$ and $\displaystyle \mathrm{E}=200 \cos \left(\omega \mathrm{t}+\frac{\pi}{3}\right)$ respectively. The phase difference between voltage and current at any instant is :
