In a series $LCR$ circuit,an alternating emf $(v)$ and current $(i)$ are given by the equations $v = v_{0} \sin \omega t$ and $i = i_{0} \sin \left(\omega t + \frac{\pi}{3}\right)$. The average power dissipated in the circuit over a cycle of $AC$ is:

  • A
    $ \frac{v_{0} i_{0}}{2} $
  • B
    $ \frac{v_{0} i_{0}}{4} $
  • C
    $ \frac{\sqrt{3}}{2} v_{0} i_{0} $
  • D
    Zero
